Question

I’m using C++ for the first time from PHP. I was playing around with some code. To my understanding cin.get(); was suppose to stop the window from closing until I press a key, however it doesn’t seem to be working because of the code before it, I don’t know what the problem is. Here is my code:

#include <iostream>
#include <cstdlib>

using namespace std;

int multiply (int x, int y);

int main ()
{
    int x;
    int y;

    cout << "Please enter two integers: ";
    cin >> x >> y;

    int total = multiply(x, y);
    cout << total;

    cin.get();
}

int multiply (int x, int y) {
    return x*y;
}

Answer 1

Put a

cin.ignore(numeric_limits<streamsize>::max(),'\n')

after >> x >> y; (or before cin.get()).

This flushes the buffer of cin and deletes the pending \n which is still there, because you cin reads x and y but also reads the last return (after y). This gets read in when you call cin.get(). If you flush the buffer cin.get() will see an empty buffer and everything is fine.
