can you help me to finish this cod in C++

main.cpp

#include using namespace std; #include "Rnumber.h"

cout General Description: 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, a. except when bis 1, then it should just display a b. or when bis 0, then it should display #divo 3. The operations that should be implemented for the rational numbers are Result 13/24 15/24 Operator Addition Subtraction Multiplication Division Invert Mixed fraction Reduce Less than Less than or equal to Greater Than Greater than or equal Equal to Example 3/8 + 1/6 3/8-1/6 3/8 * 1/6 3/8 / 1/6 3/8 I 8/3 M 6/8 R 1/6 3/8 1/6 >= 3/8 3/8 == 9/24 1/16 9/4 8/3 2 and 2/3 3/4 True True False False True 4. The arithmetic operators must be overloaded to work with the class 5. The class must have a. At least 2 private member variables, numerator and denominator b. At least 4 public member functions i. getNum().getDen(), setNum(value), setDen(value) 6. You must have internal documentation: See the handout on Documentation Standards General Description: A rational number is of the form a/b, where a and b are integers, and b is not equal 0.
