Class Diagram for Assignment No. 2
Figure 1: Object Model of Song Library System
Also note that you don’t have to give actual implementation in c++ but simple stereotype (sketch) in the form of c++ code mentioning class names their parameters and functions with access specifiers.
You also have to show the relationship (inheritance, association, aggregation, composition) between classes in proper c++ syntax with comments.
Note: Every student will follow the above mentioned Object Model in order to develop solution of assignment No.2.
