Hello.

I was wondering why this program is not compiling. Thanks

It's horrible code, but it does compile (as C, not C++). What error are you getting, and why do you think it is a Code::Blocks issue?

[Radek]

This seems to be a standard console program. No GUI in sight, only standard C. Thus, create a "console app" project, remove the main.c added to your project by Code Blocks by default, and add your code. You should pass.

Could you please explain, where this question is related to Code:Blocks, which is an IDE, not a compiler ?

If it is not related, this question violates our forum rules and wil be locked !

And please use code-tags for to embed code the next time, to enhance the readability.
I wil do this for you in your opening post.
