Winsock Math Operations client \ server

[Paul McKenzie]

However, how is it I incorporate these variables into my mathOp function to actually perform the calculation?

Your approach to this problem is backwards, to be honest with you. You should start from the "inside-out", not from the "outside-in".

The first thing you should have done is write a function that takes two double arguments, an operation, and returns the answer. It doesn't matter where the arguments came from, whether it be from a server, the keyboard, an input file, or hard-coded values from a sample main() program.

#include <iostream>

double mathOp(double arg1, double arg2, char functionToDo)
{
    switch (functionToDo)
    {
        case '*':
            return arg1 * arg2;
    }
    return 0;  
//...
}

int main()
{
   std::cout << "The answer to 3 * 6 is " << mathOp(3, 6, '*');
}

The function above doesn't care where the numbers or operation came from. Then you test the daylights out of that function, replacing 3, 6, and the '*' with other numbers, operations, etc. to make sure it works correctly.

Once you have a simple main() program working, then and only then do you now consider "client / server", parsing input, etc. The function is in place, and now it's just a matter of taking the data from wherever it comes from, and supplying the data to the function.
