    >>> how do i make them standard functions in C compiler

    "standard" functions are not in the compiler, but in a library which is linked to your compiled source by the linker. If you want to do the same thing, make a library with your functions in it and then link your code with that library.

    When you compile two or more source files, it is the linker that puts them together. As long as you have your pototypes correctly stated, i.e.that both files know what is what, you can call the function as if it were in the same file as your main().

    The details of how to acheive these things is compiler specific.
