Assignment


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



Note: you have to use same Class and Function name as mentioned in the assignment details. If we find any deviation, marks will be deducted.

Deadline:
Your Assignment solution must be submitted on or before January 24th, 2011.





Only CPP file will be accepted, file other than CPP will be awarded zero (0) marks.





SOLUTION
IDEA NOT 100% SURE

#include <iostream.h>
#include <conio.h>
class price{                 //Decelaration Class name is Price
    private:
        int rupies;
        int paisas;
                            //Public function Declaring
    public:
        price();            //Default constructor
        price (int,int);    //Overloaded constructor
        void Print();            //print function for display the array content
        price operator+(price); //Operator overloading function for operator +
  };

                      // Default constructor
price::price()
{
    rupies = 0; 
    paisas = 0;
}

                     // Overload constructor
price::price(int crupies, int cpaisas)
{
    rupies = crupies;  
    paisas = cpaisas;
}

                         //Function to display the content
 void price::Print() 
 {
    cout<<"  Price is  "<<rupies<<"  Rupees and  "<<paisas<<"  Paisas  "<< endl;
 }
 
// Function for operator overloading
price price::operator+(price d2)
  {
      int r = rupies + d2.rupies; //adding rupeies
      int p = paisas + d2.paisas; //adding paisas
      if (p>=100)                  //If paisas exceeds from 100 then adding
      {   
      p-=100;                          // then into rupies                       
      r++;
      }
      return price (r,p);     
    }
 
main()
{
price result;
price obj1(10, 60);
price obj2 (12, 80);
result = obj1+obj2;
obj1.Print();
cout<<"\n";
obj2.Print();
cout<<"\n";
cout<<"After Addition\n\n";
result.Print();
getch();


}
