//This program has one c++ function called main
//main returns an integer and requires no arguements e.g. ()

	int i = 10, j = 5;

	//use the console output routine from the std I/O namespace -- cout
	//also use the end line symbol endl from the std namespace
	//cout is an object
	// the << operator (normally left shift) is overloaded to mean put to
