The Last Words on Function Calls For Now
		• Value-returning functions – The function call is used within an expression; it does not appear as a separate statement. – The function computes a value (result) that is then available for use in the expression. – The function returns exactly one result – no more, no less. • The argument to a value-returning function can be any expression of the appropriate type. • The compiler applies type coercion if the types don’t match.
