C program to calculate simple interest

➽ Program:-

#include<stdio.h>

int main()

{

    float principal_amount, rate, time, simple_interest;

    printf("Enter Principal Amount: ");

    scanf("%f", &principal_amount);

 

    printf("Enter time(in years): ");

    scanf("%f", &time);

 

    printf("Enter rate: ");

    scanf("%f", &rate);

 

    simple_interest = (principal_amount * time * rate) / 100;

 

    printf("Simple Interest = %f", simple_interest);

    return 0;

}

➽ Output:-

Enter Principal Amount: 1700

Enter time(in years): 3

Enter rate: 6.7

Simple Interest = 341.700012
