Program 3: Show addition, Subtraction, Multiplication, Division and Remainder of any two numbers

#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int a=6;
int b=5;
int c,d,e,f;
c=a+b;
d=a-b;
e=a*b;
f=a/b;
g=a%b;
printf("addition=%d",c);
printf("\nsubtraction=%d",d);
printf("\nmultiplication=%d",e);
printf("\ndivision=%d",f);
printf("\nremainder=%d",g);
getch();
}

Output
addition=11
subtraction=1
multiplication=30
division=1
remainder=1

Explanation
Here two numbers are assigned in varriable a and b and other varriables c,d,e,f and g are declared for storing the results of addition, subtraction, multiplication, division and remainder respectively. "%" is used to find remainder. "%d" is a specifier of integer.
Here "\n" is a specifier that is used to print the text in new line.


Exercise: 
Find out  simple interest where principal is 2000, time is 3 years and rate is 2% using a C program.
