Where are C/C++ main function's parameters?

Question

In C/C++, the main function receives parameters which are of type char*.

int main(int argc, char* argv[]){
  return 0;
}

Answer 1

As pmg mentions, when main is called recursively, it's up to the caller where the arguments point to. Basically the answer is the same on the original invocation of main, except that the "caller" is the C implementation/OS.

On UNIX-y systems, the strings that argv points to, the argv pointers themselves, and the process's initial environment variables are almost always stored at the very top of the stack.
