Hi Dark,
The void main function here should indeed be void, but it is the second
function that we must look at. the add_numbers function returns an int, and
takes two arguments; two ints in this case and adds them together, returning
the result. first and second are simply variable names local to that
function which will receive the values that the user passes when calling it.
So when we call it from main we say 3 and 5 as our parameters, which means
that when the function begins executing the int variable first will have the
value 3 and second will have the value 5. In short, the parameter list has
variable types and names that get assigned the values that the user calls
the function with.
Kind regards,
Philip Bennefall

Subject: [Audyssey] Return function explain
Appologies, but I'm stil a bit lost on returning functions.
Could someone please give me a blow by blow on this example from the
tutorial sinse other than the alert function and the original void main
I'm slightly lost with this one:
void main()
{
int x=add_numbers(3, 5);
alert("Wow", "3 + 5 is... " + x + "!");
}
int add_numbers(int first, int second)
{
int result=first+second;
return result;
}
Really sorry for the question, ---- it might just be me being extremely
stupid here.
Beware the grue!
Dark.
