When you use structure and union in C ?
Structure is a user defined data type which hold or store homogeneous data item or element in a single variable. It is a Combination of primitive and derived data type.
In C language , array is also a user defined data type but array hold or store only similar type of data, If we want to store different type of data, then we need to define separate variable for each type of data. For this problem, Structure is best suit.
A union is quite similar to the structures in C. It also stores different data types in the same memory location. It is also a user defined data type same like structure. It is more near to structure. Union can be defined in same manner as structures, for defining union, use union keyword where as for defining structure, use struct keyword.
When you need to manipulate the data for all member variables then use structure. When need to manipulate only on member then use union.
All the properties of the structure are same for union, except initialization process.
In case of structure initialize all data members at a time because memory locations are different but in case of union only one member need to be initialize.
In case of union if we initialize multiple member then compiler will gives an error.
Why Android Studio ?
Android Studioo is the official IDE for Android development, and with a single download includes everything you need to begin developing Android Apps.
The reason why we should prefer Android Studio are :
-Flexible Gradle based build system.
-Build variants and multiple apk file generation.
-Code templates to help you build common app features.
-Built in support for Google Cloud Platform, making it easy to integrate Google Cloud Messaging and App Engine.
-Rich layout editor with support for drag and drop theme editing.
-Hint tools to catch performance, usability , version compatibility, and other problem.
-Official Google Support and usual updates that need no migration.
Android Versions and Android SDK Manager
Google, releases almost every year (or even sooner than a year), a new Android version in order to update the mobile operating system, so that it contains new features and possibilities and of course to fix things that might not work in the right way.
So, each version of Android has it's own SDK (software development kit), so that we can use to build apps that can run on and include all the latest features Android has added in its latest versions.
This means that it is essential that we keep up updating our applications with the latest features all the time, and it possible, without losing the consistency of the previous Android versions.
As part of the Setup Wizard you will already have the latest SDK available to you, however it's useful to know how to install additional SDK's if you need to work with the older devices that do not run the latest version of Android.
SDK's allow you to create AVD's (Android Virtual Device) to test your apps on, customized to your personal configuration.
Positive Impact computers
- Any professional individual like doctors, engineers, businessman etc undergo a change in their style or working pattern after they get the knowledge of computer. '
- An individual becomes more competent to take a decision due to computer because all the information required to take the decision is provided by the computer on time. As a result, any individuals or institutions get success very fast .
- The person working at the managerial level becomes less dependent in low level staff like clerks and accountants . Their accessibility to the information increases tremendously. This improves their working pattern and efficiency, which benefits the organization and ultimately affects the society positively.
- In common life also, an individual gets benefited with computer technology. When airports, hospitals, banks, departmental stores have been computerized, people get quick service due to the computer system.
- Computers have created new fields of employment. These employments are in the field of designing, manufacturing, teaching etc.
Monitors
The monitor is the most frequently used soft copy output device. A computer screen, that is, monitor, is a TV like display unite attached to the computer on which the output can be displayed and viewed. Images on the monitor are created by the collection of dots. These dots are known as pictures' elements or pixels. More the pixels on the monitor, sharper the picture is. The computer screen can be either a monochrome display or a color display. A monochrome screen uses only one color to display text on a contrasting background. A color screen commonly displays 256 colors.
Nowadays, users are increasingly viewing video clips, animated objects, and complex graphics. Due to this, Monitors are becoming more popular. Monitors are available in various screen sizes like 14, 15,17,19,21 inches. Notebook- computer screen sizes are usually smaller, typically ranging from 12-15 inches. Most of the monitors are made up of CRT (Cathode Ray Tube) in which the image is formed, whose pixels are coated with phosphorus, causing them to glow when hit by electron beam. CRT monitors require a lot of power to run, therefore, they are not practical to use with notebook computers. LCD monitors are flat panel monitors which create images with a special kind of liquid crystal. LCD monitors consume very less power. So, they are used in hand held computers, laptop and calculators. There are different types of display adapters that can be used in the monitor. They are classified on the basis of resolution, color, and displayed mode.
1. MDA( Monochrome Display Adapter)
2. CGA (Color Graphic Adapter)
3. EGA ( Enhanced Graphic Adapter)
4. VGA (Video Graphic Array)
5. SVGA (Super Video Graphic Array)
C program to check whether inputted number is prime number or not.
Prime numbers are divisible only by 1 and by themselves. 2,3,5,7,11 etc are prime numbers. These numbers are only divisible by 1 and by themselves. To check whether a given number is prime number or not, at first, we start a loop from 1 to given number and check as if it is divisible the loop incremented number and if it is, then we will print that given number is prime number and also if it is 2, we will directly check it and print that given number is prime number. Have a look here,
The Output
C program to display prime numbers between 1 to 100.
Prime Numbers are those which have only 2 factors; by 1 and by themselves own. For examples, the first five prime numbers are 2,3,5,7 and 11. These numbers are divisible by 1 and by themselves. Here, we have to print prime numbers from 1 to 100. So, we have to use for loop. The nested for loop works here, one by variable 'a' and another by 'b' and an increment number is also stored in 'p'.
The first loop starts from 1 and inside it, another loop begins until the value of b becomes greater then a. If the remainder when a is divided by b becomes 0. The value of p incremented by 1. If the value is 2 means that first loop also has moved for 2 and value of a is 2. And, so it get printed. The first prime number is extracted and now whenever the divisible of a by b becomes 0, the value inside a gets printed and we will get all the prime numbers.
The Output

Microwave System
Microwave system use very high frequency radio signals to transmit data through space (wireless communication). Transmitter and receiver of a microwave system mounted on very high towers, and should be travel almost straight line (should be line of sight). This may not be possible for very long distance transmission . Moreover, signal become weaker after traveling certain distance and require power amplification. Microwave system uses repeater at interval of about 25 to 30 km in between transmitting and receiving station. It is placed on tall building to avoid obstacles. It can support 250,000 voice channels simultaneously. It's installation charge is high.
It is of two types :
i) Terrestrial Microwave : A Ground stations that receives microwave signal, amplifies them and pass them on to another station are known as terrestrial microwave station. The distance between stations is between 25 to 30 miles. Parabolic antennas are used to transmit and receive to each other.
ii) Satellite Microwave : Satellite transmission : A satellite is an object build and placed by human in Earth orbit. It is a specialized wireless receiver/transmitter that is launched by a rocks and placed in the orbit around the earth. There are hundreds of satellites currently in operation. They are used for such diverse purpose as weather forecasting., television broadcast, amateur radio communication, internet communication. Hundreds of satellites are now in orbit to handle international and domestic data, and video communication needs.
Simple Mail Transfer Protocol (SMTP)
Simple Mail Transfer Protocol (SMTP) is the standard protocol for email services on a TCP/IP network. SMTP provides the ability to send and receive email message.
SMTP is an application layer protocol that enables the transmission and delivery of email over the internet. SMTP is created and maintained by the Internet Engineering Task Force (IETF).
Simple Mail Transfer Protocol is also known as RFC 821 and RFC 2821.
SMTP is one of the most common and popular protocols for email communication over the Internet and it provides intermediary network services between the remote email provider or organizational email server and the local user accessing it.
SMTP is generally integrated within an email client application and is composed of four key components :
1. Local user of client end utility known as the mail user agent (MUA).
2. Server known as mail submission agent (MSA).
3. Mail Transfer Agent (MTA).
4. Mail Delivery Agent (MDA).
SMTP works by initiating a session between the user and server, whereas MTA and MDA provide domain searching and local delivery services.
Android
Android is a mobile operating system currently developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android offers unified approach application development for mobile devices.
Android is an open source operating system. Google has made the code for the low-level "stuff" as well as the needed middleware to power and use an electronic device, and gave Android freely to anyone who wants to write code and build the operating system from it. There is even a full application framework included, so third party apps can be built and installed, then made available for the user to run as they like.
Android Programming
Lots of people, are now engaged in developing android mobile application because of the reason that android has become most popular mobile operating system, with almost 2 billion devices activated.
Developers are more interested to show there invention to the world and its the easy to reach more people through android mobile application development ,as almost, all the people are using devices that embed Android Operating system. Application developed for android operating system can run on Android powered TV sets or Android Car system and this is the reason, Application developed for android operating system has endless boundaries.
In this series of course, we will be able to be familiar with Android IDE and can be able to make an android app and we can place ads in our app and so we can earn more and more money though it.
Just follow the series and make comment so that, I can solve your problem.
Function In C
A function is a group of statements that together perform a specific task. Function is a block or part of program. A function definition specgifies the name of the function, the types and number of parameters, it expects to receive, and its return type, when any program is very long or same code is repeating many times then we try to cut the program in different parts(blocks) so that whole program become more understandable, easier to debug and size of code will be shorter. A repeated group of instruction in a program can be organized as a function. Every C program has at least one function, which is known as main() function.
Why to use function?
Advantages of Function
Defining of function is nothing but give body of function that means write logic inside function body.
Syntax
return_type_function(parameter)
{
function body;
}
Return type : A function may return a value. The return type is the data type of the value the function returns. Return type parameters and return statement are optional.
Function name : Function name is the name of function. It is decided by programmer or you.
Parameters : This is a value which is pass in function at the time of calling of function. A parameter is like a placeholder. It is optional.
Function body : Function body is the collection of statements.
Function Declarations
A function declaration is the process that tells the computer about a function name. The actual body of the function can be defined separately.
Syntax :
return_type function_name();
Calling a function
When we call any function, control goes to function body and execute entire code. For call of any function, just write name of function and if any parameter is required then pass parameter.
Syntax:
function_name(); or
Varriable=function_name(argurment);
Why to use function?
Functions are used for driving a large code into module, due to this we can easily debug andd maintain code. For example if we write a calculator programs at that time we can write every logic in a separate function(for example sum(), for subtraction sub()). Any function can be called many times.
Advantages of Function
- Code Re-usability
- Develop an application in module format
- Easily debug the program.
- Code optimization: No need to write lot code.
- Program testing becomes easy.
- Compiled executable is smaller.
- You don't have to make comments because function name make sense.
- Program can be developed in short period of time.
- There is no chance of code duplication.

An Array in C programming
An array is a collection of similar data type which is stored in a consecutive memory location in a single variable. It is derived data type in C, which is constructed from the fundamental data type of C language. The individual values in an array are called elements. If it contains int data type then all the data of the array must be int, if float then all the data must be a float.
Each array element is referred by specifying the array name followed by one or more subscript with each subscript enclosed in square brackets. In C subscript starts at zero rather than one and each subscript must be expressed as a non-negative integer. The subscript is used to denote the size of the array.
.
Advantages of array
Syntax
datatype arrayName[SIZE]
Example
int rollno[20];
rollno varriable can store 20 values in it.
Initialization of array
Initializing is a process to initialize the value in array variable. This is happen in two ways, initialize array one by one or all elements initialize once.
Initialization array one by one
int rollno[3];
rollno[0]=4;
rollno[1]=2;
rollno[2]=5;
Initialization array at once
int roll[]={4,2,5};
roll[2] // here 2 is index value and return 5;

- The array has 0 as the first Index.
- If the size of an array in n, to access last element, [n-1] index is used
Program To Print Multiplication table of 2, 3 and 4
To print the multiplication table we have to use for loop. Inner loop is used here where two varriable are plays vital role i.e. i and j. Symbolic letter "x" and "=" are also being used to give illusion of multiplication.
So, the program begins here
This program takes two varriable i andd j and are multiplied in the inner loop. In a first loop the value of i remains same while the value of j increases by 1. Integer specifier are used. Here new line is printed as the loop of j ended the new line begins.
Output
Here, all the multiplication table is not shown because the output window is small.
So, the program begins here
Output
Program to print 2 3 4 5 6, 4 5 6 7 , 6 7 8 , 8 9 , 10 [Nested for loop]
Output
Explanation
Here, nested for loops is used. The varriable i initialize from 1 and then passes through next loop j and it gets continue to execute the statement that is inside the j block until the condition of j loop gets false. In the first loop of j, the value of i is 1 which is equal to the initialization of j and prints the addition of i and j i.e 2. Next time, the value of j increase to 2 but the value of i remains same as 1 and prints the addition of i and j i.e, 3 and at last loop of j the value of j reaches to 5 but still the value of i is 1 and prints the addition of i and j, i.e, 6. When the condition gets false, steps goes outside the loop and it meets the statement that prints next line. Since, the condition of loop of first loop of i is not false, the loops begins agai. This time the value of i is 2 and passes inside the j loop. And the loop of j begins again to print another statement.
Program to print odd numbers less than 20 using for loop.
Explanation,
Here, i is initialized with value and in every loop, value in i increase by 2 until the condition gets false.
Output
Exercise:
Print even number less than 30 using for loop.
Program to print multiplication table of given number
Explanation
In this program, n stores a number and i is an increment. The loop start from 1 and ends on 10. Inside printf, the format %dx%d=%d, here %d are replaced by the value of n which is constant, i that is incremented in every loop and n*i which yields product of n and i. Here, x remain same till the program that makes a multiple sense in the output.
Program to print sum of first ten natural numbers
Explanation
Here the variable s denotes to sum and is initialized with value 0. When the loop begins, the s adds the value of i with its previous values along with the loop.When the loop terminate, the last sum is stored in s and is printed outside of the loop.
Output
Program to print 'n' numbers using for loop
Explanation
Here, in the program, two variables are used n and i. n stores number inputted by user and "i" is used as loop. As the loop increment it will print the value of i until it becomes greater than number stored in n.
Output
Exercise
Make a program that will print "*" for n times using for loop.
Covid-19 and Antiviral Drugs
Dozens of clinical trials are launched by many doctors and researchers since this pandemic broke through. But, these multiple trials are not giving strong evidence to save a life from novel Corona Virus. Though, The WHO is launching multi country clinical trials to test four drug regimens as COVID-19 therapies; remdesiver, chloroquine, a combination of two HIV drugs, and those same two HIV drugs along with the anti inflammatory interferon beta. The US is not currently involved in WHO trials.
Hundred of clinical trials are underway, and other groups are adopting the medications that the WHO selected.
Several Tests have the following results on the medications that WHO selected.
Remdesivir was used for the treatment of Ebola, and the research also showed that this can also be used to block SARS and MERS. Research also showed that it could inhibit the novel Coronavirus in cells.

Corona Virus(Covid-19)-How to use Mask?
Corona Virus disease(Covid-19) is a disease caused by corona virus that causes illness including common cold to more severe disease and even death. Covid-19 is a new strain that discovered in 2019 from the city of Wuhan(China). Common Signs are fever cough, shortness of breath and difficulty in breathing as well as in some cases pneumonia, severe acute respiratory syndrome, kidney failure and even cause death of victims.
Personal Hygiene is a must to be away from this virus. I am going to point some basic way to properly use mask.
When To Use Mask
- If you're taking care of victim of covid-19.
- If you are coughing and sneezing
- It is better to use while you are properly and regularly washing your hands with alcohol based hand rub or soap and water.
- While using mask, you must know how to use it and how to dispose it properly after using it.
- Before putting on mask, properly wash your hands with alcohol based hand rub or soap and water.
- Cover your mouth and nose properly and be sure that there is no gaps between your face and mask.
- Avoid touching your mask frequently: if so, wash your hands with alcohol based hand rub or soap and water.
- Replace the mask as soon as it is damp.
- To remove mask, remove it from back, don't touch the front of the mask. Discard it immediately in a closed recycle bin.
Goto Statement or Jump statement in C
The goto statement is also known as jump statement that makes a program procedure to jump any where from anywhere within the program. It is sometime also called unconditional jump statement.
In this program, it takes name of a person and then prints it. Here "jump:" is a label that goto statement will transfer the step when encountered. So, after printing the name, it asks to continue and if a user enter y or Y the goto statement transfer the step to that label and if any other key is pressed the program will print Visit Again.
Break and Continue in C
Break statement when encountered in the loop it immediately break the loop and program resumes at the line following the loop. It also terminate the case statement in switch.
For example, if we are writing a program to search a name among 1000 of given names, we may have applied loop for this program, . But if the program finds it in 10th iteration and at this point, we don't need to travel for remaining 990 iteration, we just need to terminate the loop and resume the program outside the loop. For this, only break statement is useful.The break statement is used in conjunction with condition.
For example,
In this program, i increases by 1 and when it encounters with number 5, it gets broken and the loop gets terminated.And thus, the output will be 1 2 3 4
Continue statement is used to omit a particular statement and proceed to next iteration. The continue statement escape the statement and move to next iteration.
For example, if we have to escape 10th number from 1000, continue statement is used. It is used in conjunction with condition.
Here, the for loop continues and when i is equal to 5, it step escape the statement and move to another iteration. Hence, from the program the output is 1 2 3 4 6 7 8 9

Looping
Loop is used in programming to execute any instruction repeatedly until a condition is satisfied. The computer has ability to perform a set of instructions repeatedly. This involves repetition of some portion of a program either for a specified number of times or till a given condition is satisfied. This repetition operation is known as looping.
Purpose of Looping
It execute one or more statements while the given condition remains true. It is useful when number of iterations is unknown. It is also called entry control or pre test loop.
do while Loop
do while loops are useful where loop is to be executed at least once. In do while loop condition comes after the body of loop. The loop executes one or more statements while the given condition is true. It is an exit control or post test loop.
For loop
For loop allows to specify three things about loop in a single line. For loops are used when the number of iterations is known before entering the loop. It is also known as counter controlled loop.
Purpose of Looping
- To execute statements for a specified number of times.
- To use a sequence of values.
- While Loop
- do while Loop
- For loop
It execute one or more statements while the given condition remains true. It is useful when number of iterations is unknown. It is also called entry control or pre test loop.

Social Medias on Corona Virus
Nowadays, social medias such as Facebook, Twitter, Instagram are full of information related to Corona virus. Almost everyone in the world are using these medias and getting information related on this viral topic. But, mean while since the information are shared by anyone may create confusion on the information related Corona virus since a false news are also been posted there. Social medias are need to be consider for this and should make a necessary steps to filter the information on the serious sensitive information. People are becoming panic and are afraid very much since they are getting wrong information. They are in dilemma of either their locality has become prey of the virus or not, either the vaccine are made yet or not, either they are safe to travel to foreign or not, either the precaution they are using is better or not and so on.
A large masses of people are sharing the wrong information day by day in Facebook. Many more TV channels are making it as source of income spreading the fake information whatever they are getting without any research or fact. The social medias should make necessary steps for this activity and should provide right information from WHO. I think they should play vital role in spreading right information on Corona virus and should come in real world to save humanity and save the world from this epidemic.

Program to check whether a entered letter is vowel or not using switch case statement
Explanation
Here Switch case plays a role of nested if else statement. It is an alternative way of if else statement. In this program, a variable c is declared to store alphabet entered by user. And now case is applied, if the given letter matches to the case then it enters to its block and print the given statement and then break the procedure. If the case is not matched it will check another case and if not matches all the cases then it will enter to in the default block.

Discussions on Coronavirus.
What is Coronavirus? Define Covid-19.
The epidemic Coronavirus is a acute respiratory syndrome virus while the disease associated with it is known as Covid-19. It is a type of virus that is circulated in animals. After they have affected to animals eventually they are transmitted to humans. A wide range of animals are the sources of this virus. For example Middle East respiratory syndrome Coronavirus come from camels and severe acute respiratory syndrome Cornovirus come from civet cats.
