C Program to Calculate Simple Interest

In this example, we take user input and calculate simple interest.

Calculate Simple Interest In C Programming

	
#include <stdio.h>  
int main()   
{   
    float p , r , n , simple_interest ;  
    printf("Enter Principle Amount :: ");
    scanf("%f",&p);
    printf("Enter Interest Rate :: ");
    scanf("%f",&r);
    printf("Enter Year :: ");
    scanf("%f",&n);

    simple_interest  = (p * r * n)/100;   

    printf("\n\n Simple Interest is : %.2f", simple_interest);  
    return (0);  
}  
    

Output :

	
Enter Principle Amount :: 100
Enter Interest Rate :: 10
Enter Year :: 2
Simple Interest is : 20.00
