Product of Two Numbers Using Classes in C++

Here is a simple code that I wrote a long time ago while I am working as a college professor in one of the University in my hometown. I was teaching C++ programming from the basics to advance topics. Below is a code the shows how to use classes to find the product of two number being provided by the user. I am using Dev C++ as my C++ compiler in writing this program and CodeBlocks as my text editor. I hope you will learn something from it. Thank you.

Program Listing

#include <iostream>

#include <string>

using namespace std;

class multiply {

    int val1,val2;

    char reply;

    public:

    int get_data();

    void display_result(void);

};

int multiply :: get_data()

{

    while (1) {

    system("cls");

    cout << "enter two number :";

    cin >> val1>> val2;

    cout << "\n\n The Product is " << (val1*val2);

    cout << "\n\n";

    cout << "More Y Or N : ";

    cin >> reply;

    if (tolower(reply) == 'n') {

        cout << "Thanks";

        break;

    }

    }

}

void multiply :: display_result(void)

{

    int val=0;

    val = get_data();

}

main() {

    multiply numbers;

    numbers.display_result();

}
