What is Function? Write a program to demonstrate any two string function using C.
A function is a block of statements that performs a specific task. In c, we can divide a large program into the basic building blocks known as function. The function contains the set of programming statements enclosed by {}. A function can be called multiple times to provide reusability and modularity to the C program. In other words, we can say that the collection of functions creates a program. The function is also known as procedure or subroutine in other programming languages.
What is Array in C? Write a program to sort numbers in descending order.
- An array is a collection of data items, all of the same type, accessed using a common name.
- A one-dimensional array is like a list; A two dimensional array is like a table; The C language places no limits on the number of dimensions in an array, though specific implementations may.
#include <stdio.h>void main ()
{int number[30];
int i, j, a, n;
printf("Enter the value of N\n");
scanf("%d", &n);
printf("Enter the numbers \n");
for (i = 0; i < n; ++i)
scanf("%d", &number[i]);
/* sorting begins ... */for (i = 0; i < n; ++i)
{for (j = i + 1; j < n; ++j)
{if (number[i] < number[j])
{a = number[i];
number[i] = number[j];
number[j] = a;
}}}
