	//Need {curly braces} around the body of this if statement:

	if (i > 0) {
		cout << i << " is positive\n";
		cout << "-- -- --------\n";      //underline

	//Don't need {curly braces} around the body of this if statement:

	if (i > 0) {

	//So you could write the above if statement as follows:

		cout << i << " is positive\n";
