// Simple Interest Program in C using Function
#include <stdio.h>

// This function will calculate the simple interest
void CalcSimpleInterest(float x, float y, float z) {
    float SI; // value of the simple interest

    // It will calculate the value of simple interest
    SI = (x * y * z) / 100;

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

// It's the driver function

    scanf("%f%f%f", &p, &t, &r);
