    Question Newbie Question1

    Ok Guy's,
    I am needing to know what functions do the following:

    Give me a block of memory
    Tells me a character is not a space ( )

    Also, if anyone could direct me to a website that list's all available functions and their purpose I would greatly appreciate it.

    Thanks...

    Give you a block of memory? calloc() and malloc() (stdlib.h)
    Tells you when a character is not a space? isalnum() (ctype.h)
    Also you could simply say !isspace() (ctype.h)

    Hey C,

    The isalnum() and isspace() are showing as C++ functions not C. Are they the C functions as well or is there a function for the C language as well?

    Yes, they're there, in the ctype.h (a C header file).
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.
