#include <stdlib.h>     // TO GET THE GLOBAL _arg VALUES

using namespace std;

void func()
{
   cout << "argc= " << _argc << endl;

   for (int i = 0; i < _argc; ++i)
      cout << _argv[i] << endl;
}

void main(int argc, char ** argv)
{
   func(); // func can get the program arguments from global variables.
}
