// C++ program to enter the P, T, R, and calculate it's Simple Interest
#include <iostream>
using namespace std;

int main() {
    float p, t, r, SI;
    // p = principal
    // t = time
    // r = rate
    // SI = simple interest

    cout << "Enter the principal (amount), time, and rate::\n";
    cin >> p >> t >> r;

    // Calculate simple interest
    SI = (p * t * r) / 100;

    // Output
    cout << "\nSimple Interest = " << SI;
    return 0;
