Thread: Is it possible to change the value of a variable in main using a function?

Hi, I'm currently writing a poker game and am trying my best to avoid using global variables. I have a few variables in int main() which i was hoping to use to store the value of each players hand. I then created a function which calculates the value of the hand but cannot get this value back into the main function.

For example:

Code:

#include <iostream>


using namespace std;


void getValue(int value)
{
    value = 4;
}


int main()
{
    int value;


    getValue(value);
    cout <<"the value is: " <<value;
}

Is there any way i can get the value of value using this function?
If not what do you suggest i do?

Thanks
