int main( int argc, char *argv[] )
{
	// This prints out the command-line arguments in order.
	// Note that argc counts the command name itself as
	// one argument.

	for( int i=0; i < argc; i++ )
		cout << "argv[" << i << "] = " << argv[i] << endl;


	// Here's how programs that use command-line arguments
	// often begin.  For this example, I'll assume the program
	// is expecting two command-line arguments (in addition
	// to the command name): a dictionary file name and a
	// text file name.
	
	if( argc != 3 )
	{
		cerr << "Usage: " << argv[0] << " dictionaryFile textFile" << endl;
		exit(0);
	}
	
	
	// Now move on with the rest of the program.

	cout << "Nice job.  The right number of arguments." << endl;
