anybody know what's int means on the main method? Does that represent anything? Why is it int? I'm pretty sure that's not return value right??? aish...

Int means integer, main(), is returning an Integer, hence the int. When It says return, that means that when you say "return 0" in your code. So basically, until it gets to the return statement, it knows that it's job isnt done yet, when it sees that, the "return 0" it knows it has finished.

hope that helps

oh yeahhh!!! I just saw that there's a return 0 there sigh.. let me try with void then thanx a lot Lee
I'm now playing around with C++

your welcome, im a fellow noob at C++, learning as i go i suppose, glad i can offer help and im not totally useless at this area XD

I think void main() is out of date. Much of programmers suggest that using
int main() instead of void main(). Honestly, I don't know why too. Anyway,
you don't need to return any value in main() function. It is exceptional.
However, it is recommented to return value.

The C++ language definition requires that main return an int. To do otherwise is incorrect C++, but many compilers allow it for various reasons, such as tradition, backwards-compatibility and because allowing it extends the language in a way that doesn't affect any other part of it.

It is customary for the return value to indicate success, usually by returning zero, or to give an error code that can be used to debug.

Would the compiler return some kind of an exception if we don't put int return value in the main method? Well, I personally interested in C# more than C++ though for ASP.NET, but I'm just wondering at least to add up for my knowledge

A compliant compiler will either display an error and refuse to compile the program or compile the program after issuing a warning about the practice.

As somebody already mentioned, returning an integer rather than nothing at all is better because then you can determine whether the program exited due to errors. In fact, on many Linux machines, you can print out a special variable to determine the exit success:
g++ -std=c++98 -o myprog myprog.cpp && myprog
# the program output is here
echo $?
# if $? shows 0, then myprog exited fine (it exited with 0 errors)

As a side note, this is contrary to many other programming implementations, such as the Windows API, where if you return 0 from a function, that means that the function did not exit successfully (did you exit successfully? 0/FALSE).

do you also create linux application with C++
Cuz I've also been wondering with this a while back ago to what language do you use to create a linux application..? Because as you see, windows is really popular because many developers are program their application using C++ or whatever else, while I don't see any specific language that's dedicated to create a linux application. That's one part that my friend and me researching about for his graduate studies

Well, it depends on which compiler you are using. If you want to know for sure for any given compiler, do it and see what happens. Some will refuse to compile, some will give you a warning but compile anyway, some will compile without mentioning that you've coded against the standard. Needless to say, a compiler that doesn't tell you when you're making mistakes and compiles around it is not something to wish for.

An 'exception' occurs during run-time. Your compiler will give you errors or warnings.
