Incrementing variables clarification needed!

[pghsteelers]

I understand the general explanation of the expression variable++ or ++variable as in when the variable is incremented during the carring out of an expression. However, can someone clarify how it occurs when being passed as a parameter in a function such as:

y = functionName(var1, ++var2);

as apposed to

y = functionName(var1, var2++);
...
...
...
int functionName(int var1, int var2)
{
sum = var1 + var2;
return sum;
}


Thanks in advance

Wow, nice site. I think I will be implementing a reading(or two) from this site everyday.

If you want to avoid confusion, just call the function and increment the variable on two separate lines. There is no increase in compiled efficiency by putting it in a single statement; it merely saves you a few keystrokes.
