Simple Interest Calculator in C

Introduction

Calculating simple interest is a common financial computation. This program takes principal, rate, and time as inputs to compute interest.

Program

#include <stdio.h>
int main() {
    float principal, rate, time, interest;
    printf("Enter principal amount: ");
    scanf("%f", &principl);
    printf("Enter rate of interest: ");
    scanf("%f", &rate);
    printf("Enter time (in years): ");
    scanf("%f", &time);
    interest = (principl * rate * time) / 100;
    printf("Simple Interest = %.2f", interest);
    return 0;
}

Explanation

• (principal * rate * time) / 100: Formula to calculate simple interest.

• %.2f: Formats the output to two decimal places.
