UML class diagrams show how each parameter is to be passed to the method. Each parameter is prefaced whith either in, out or in out. If a parameter is to be passed by value, in is specified. If a parameter is passed by referenced but he initial value is not to be used, "out" is specified. If the initial value is used but the parameter is still passed by reference, in out is specified. There are lots of tools to create UML diagrams including Microsoft Visio and Dia. Other supporting methods can be added to the class diagram as needed. Below is a code fragment that demonstrated how the mathematical method calls should be performed. Fraction f1 (1, 2) f2 (3, 4), f3: f3. Multiply (f1, f2); f1.Display(); cout
