C++ A rational number is of the form a/b, where a and b are integers, and b is not equal 0. Develop and test a class for processing rational numbers.

Details:

1. Your program should have 3 files: a driver file to test the operations, a header file for the class definition and any operator overloads you need, and an implementation file with the definitions of the items in the header file.

2. The class should read and display all rational numbers in the form a/b,
   1. except when b is 1, then it should just display a

or when b is 0, then it should display #div0

The operations that should be implemented for the rational numbers are:

Addition

Subtraction

Multiplication

Division

Invert

Mixed fraction

Reduce

1. The arithmetic operators must be overloaded to work with the class
2. The class must have
   1. At least 2 private member variables, numerator and denominator
   2. At least 4 public member functions
      1. getNu(), getDe(), setNu(value), setDe(value)
