// C++ program to enter P, T, R, and calculate Compound Interest
#include <iostream>
#include <cmath>
using namespace std;

int main() {
    float p, t, r, CI;
    // p = principle
    // t = time
    // r = rate
    // CI = compound interest

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

    /* Calculate compound interest */
    CI = p * (pow((1 + r / 100), t));

    // Output
    cout << "\nCompound Interest = " << CI;
    return 0;
