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
