// Simple Interest Program in C based on Given Values
#include <stdio.h>

int main() {
    float p, t, r, SI;
    // `p` = principal, `t` = time, and `r` = rate
    // `SI` = value of the simple interest

    printf("Enter the principal (amount), time, and rate::\n");
    scanf("%f%f%f", &p, &t, &r);

    // It will calculate the value of simple interest
    SI = (p * t * r) / 100;

    // It will produce the final output
    printf("\nSimple Interest = %.2f\n", SI);
    return 0;
