    Yo son, whats the deal with cerr << " "; ?

    What exactly does it do really?

    in C its like:
    fprintf(stderr, "Couldn't upload image %s: %s", filename, SDL_GetError());

    In a chatroom someone told that the C++ equivilant is:

    cerr << "Couldn't upload image " << filename << ": " << SDL_GetError();

    Some questions.
    Is it possible to use some C++ coding in the SDL graphic library?
    What is the difference between cerr and cout? if any?

    BomberLAN is written in C++ and uses SDL. cerr prints stuff to stderr, cout prints stuff to stdout.

    It's easy actually. I don't know what compiler you are using (console output works by default in gcc/linux). If you are using MSVC, you need to change the subsystem line in the project options to console.
