    Char/Const char

    What's the difference, in functions like fopen()

    Code:
    fopen(const char *filename, const char *mode)
    and functions without const, between a char and a const char or const int and the like? Thanks.

    The difference is that they guarantee that the data you pass won't be modified. What else?
