Well, you could be tricky w/ the linker and name it something else if you were *really* determined too, but essentially, yes, every ANSI/ISO compliant program must contain a main() function ... not that sometime auto-generated code, for example Win32 project code created by the Visual C++ 5/6 IDE does *not*, however it has a main() funtion in the standard libraries it imports for you.

 HOWEVER you do NOT need to *end* your program in main(). your "void main()" can go anywhere in your program you like ... AFAIK the ending your program w/ main() was an old Pascal convention. I like to have my main() function at the beginning of the file it's in, but that's just personal preference.
