n00b here. Just started learning C a couple of days ago. I'm using xcode alternatively with emacs. My question is in regards to the main function. Everytime I create a project (standard command utility) with xcode, my main function starts out looking like this: int main(int argc, const char * argv[]) What's all this in the parenthesis? Why use this rather ...

10. C: about main() vs main(int argc,char *argv[])    forums.devshed.com

It comes to you courtesy of the main() start-up routine (typically) written for you by the compiler writers. argc, argv, (and envp, a pointer to a NULL terminated array of NULL terminated character arrays) (all optional names, btw, just the types are fixed) are optional. The pre-main() code will create the data, but you won't be able to access through those ...
