C++ only

Lets start with a simple task. You are making a very simple program to keep track of gold bars for a goldsmith.

Make a class called GoldBar with the following data members or properties:

Weight (in grams)

Karats (integer value)

Price (in PKR)

You also need to make the following member functions:

Constructor function with three parameters corresponding to the three properties.

A destructor function.

Setters and getters for the three data members

Overload == operator so that it compares two objects of this class using the three properties (weight, karats, and price). If all three are equal then it returns true, false otherwise.

Overload < and > operators so it compares two objects of this class using their prices.

Overload += and -= operator so that the weight of the object can be incremented or decremented by an amount in grams given on the right-hand side of the respective operator.

Add appropriate code in the main function so that it can demonstrate the functions of the class.
