Program to calculate simple interest in c++

C++ Program to calculate simple interest. Here more solutions.

// Include header file
#include <iostream>
using namespace std;

// C++ program for
// Calculate simple interest

// Method which is take three parameters
// And calculates that simple interest
// Here time is form in year
// rate is form of annual interest rate
void simpleInterest(double principle, double time, double rate) {
    // Display parameters values
    cout << "Principle : " << principle << endl;
    cout << "Time : "      << time << endl;
    cout << "Rate : "      << rate << endl;
    // Calculate interest
    double amount = (principle * time * rate) / 100;
    // Display amount
    cout << "Simple Interest : "  << amount << endl << endl;
}

int main() {
    // Test Cases
    simpleInterest(1500, 3, 7.3);
    simpleInterest(170.4, 7, 3.4);
    return 0 ;
}

Output

Principle : 1500
Time : 3
Rate : 7.3
Simple Interest : 328.5

Principle : 170.4
Time : 7
Rate : 3.4
Simple Interest : 40.5552
