Question

2.(a) Fraction Operators Objective:

In class we discussed how to overload the + operator to enable objects of type Fraction to be added together using the + operator. Extend the Fraction class definition so that the -, * and / operators are supported. Write a main function that demonstrates usage of all of these operators.

(b)More Custom Types Objective:

Define a set of classes that represent a Schedule and Course in the context of a university student who has a schedule with a set of courses that they are enrolled in. You may define whichever properties you think are best for such a data type. Demonstrate usage of these data types in a main function.
