//
// summary: Your first program, simple output, preview of argc/argv
//
// Goals:
//
// 1 -  get this program to run (compile, link, and run it. Don't forget
// the extra steps needed on the VAX to get command line arguments working)
//
// 2 - What does this program do?
//
// 3 - add some useful comments once you figure out what it does (feel
// free to add empty lines to break the code up into logical pieces)
//

#include <iostream.h> // for i/o library

int main(int argc, char *argv[])
//argc somehow contains the number of arguments for main()
//argv[0] apparently points to the executable file name
{
        cout << "Hello world:\n"; // prints message to screen then newline
	cout << "Some more information:";//no newline
	cout << 
	"this program was called with "<<argc-1<<" arguments, while the\n"
	"name is apparently: \"" << argv[0] <<"\"\n"
	"What do you think?\n";
	if (argc > 1)
		cout << "1st arg is \""<<argv[1]<<"\"\n";
	return 0;
//if other arguments are added 1st is identified by argv[1] and printed to
//screen, however, when I added another variable to the arguments of main,
//the name output was (somthing like) "home=home/wiest_m".
