    Whats best way to loop a program?

    I have a simple little program that I created to test a funtion that best goes back to the beginning of the code from the end. Any ideas?

    Heres just a simple program:
    Code:
    #include "stdafx.h"
    #include <iostream>
    
    int ReadNumber()
    {
        using namespace std;
        cout <<" Welcome to Jake's Calculator, enter in two numbers to be computed" << endl;
        cout <<" Answers will be shown in this form: Add, Subtract, Multiply, and Divide." << endl;
        cout <<" Enter numbers to calculate:" << endl;
        int x;
        cin >> x;
        return x;
    }
    void WriteAnswer(int x)
    {
        using namespace std;
        cout <<"The answer is " << x << endl;
    }
    int main()
    {
        int x = ReadNumber();
        int y = ReadNumber();
        WriteAnswer(x+y);
        WriteAnswer(x-y);
        WriteAnswer(x*y);
        WriteAnswer(x/y);
        system("pause") // What to do from here to loop to top?
        return 0;
    }

    look into do-while or just while loops. google and this site's tutorials are an excellent source of information.
