// Example of passing arguments into main
// You may see the 'main' function in a C/C++ program with some
// arugments, namely argc and argv[], these are two default parameters that
// describe the command line arguments that invoke the program.  argc is an integer
// that tells you how many arguments there were and argv holds a pointer array
// with the program name and command line tokens.  The example below shows how it
// can work.  From the DOS prompt, just type in "argpassing hello world" and 
// you should see the following output:
// The name used to start the program: argpassing
//  Arguments are:
// 1: hello
// 2: world
// Also see: Appendix G that comes on the CD with the textbook
