Using what you already know about

Functions
Input
IF statements
WHILE loops
Return values

give it a try and we can help you. Do what that Yellow on Red post titled Read This explains.

CPP / C++ / C Code:

#include <iostream>

using namespace std;

int GetIntFromUser()
{
    int integer = 0;
    while( integer == 0 )
    {
        cout << "Enter a non-zero integer: ";
        cin >> integer;
    }
    return integer;
}

int main()
{
    int i = GetIntFromUser();
    cout << "User entered: " << i << endl;
    return 0;
}

Output:

Code:

Enter a non-zero integer: 0
Enter a non-zero integer: 192182
User entered: 192182
