    main()

    Has anyone ever tried to make this a data type besides int or void? Like this:

    char main()
    double main()
    What will people say if they hear that I'm a Jesus freak?
    What will people do if they find that it's true?
    I don't really care if they label me a Jesus freak, there is no disguising the truth!

    NO!!!!

    The ANSI standard for the main function is:-

    int main(int argc, char *argv[])

    ie returns an integer. This is why the main function always terminates with return 0;

    a lot of compilers allow you to miss out the return data type and just declare main(), and some compilers (wrongly) allow you to declare main as void.

    I suspect that if you tried to return a character (if it got past the compiler) the os would interpret it as an integer and throw up an error message.
