P5.2 Given the following student class interface, a) implement all member functions of the class, b) implement all non-member external functions of the class, and c) write a main() function to generate an output similar to the sample output appeared after the class interface. Notice that not all pre- and post-conditions for functions are provided; some are intentionally left out for you to fill in.
