C Program to Find Simple Interest

How to Calculate Simple Interest?

Simple interest can be calculated using the formula: Simple Interest SI=(p*t*r)/100.

Here p is the principle amount. For this amount we are calculating the interest. t is the timeperiod and r is the interest rate.

Take input of p,t and r then multiply them and after that divide them by 100 and which results in rate of interest.

C Program to Find Simple Interest

#include<stdio.h>
int main(int argc, char const *argv[])
{
	int p,t,r;
	printf("\n\n\tEnter principle, time and rate of interest:\n\t");
	scanf("%d%d%d",&p,&t,&r);
	float interest=(p*t*r)/100;
	printf("\n\tInterest amount is %f\n\n",interest);
	return 0;
}

Output:

	Enter principle, time and rate of interest:
	1000 1 25

	Interest amount is 250.000000

Code Explanation

In this program, the user is asked to enter principle, rate of interest, and time period.

Interest is calculated using the formula I=PTR/100 and stored in the variable interest.

Interest is printed onto the console.
