Problem Statement: Price manipulation You are required to create a class in C++ named Price with the following Data members, Data members should be publicly declared. • Rupees • Paisas The Price class presents Price in Rupees and Paisa. For instance, Price (10, 80) means 10 rupees and 80 paisas. The Price class should have the following features as described in detailed descriptions:

Detailed Description:

Constructors

Class Price must have

• Default constructor, which must set Rupees and Paisas to zero.

• Parameterized constructor that receives two parameters of type int and initializes its private data: Rupees and Paisas with them. Note that if Paisas are 100 or greater than 100 then also convert it in Rupees.

Member Functions

• Create a function named Print()that displays the price of object in terms of rupees and paisas.

Operator overloading

• A member function that overloads the + Operator to add two objects of Price.

There should be an overloaded + operators:

• Add two objects and return Price object. Note that Paisas should not exceed 100.
• Add first number into second objects and return Price object. Note that paisas should not exceed 100.

Output of your program should be as follows:

Price is 10 rupees and 60 paisas

Price is 12 rupees and 80 paisas

After Addition

Price is 23 rupees and 40 paisas
