Question

The lab for this week will be on operator overloading. Design a class named Arr that has a private member named scores as an array of size 5 of integer and do the following requirements:

1- Overload the ++ operator to increment each item of the array by 1.

2- Overload the -- operator to decrement each item of the array by 1.

3- Overload the + operator to add a bounce of 5 points for each item of the array.

4- Overload the operator >> instream operator to inter the values of the array.

5- Overload the operator << outstream operator to print the values of the array.

Explanation / Answer

#include<iostream.h>
#include<stdlib.h>

class Arr
{
private:
   int scores[5];
public:
   Arr()
   {
       for(int i=0;i<5;i++)
       {
           scores[i]=i+1;
       }  
   }

   void operator++()
   {
       for(int i=0;i<5;i++)
       {
           scores[i]=scores[i]+1;
       }
   }

   void operator--()
   {
       for(int i=0;i<5;i++)
       {
           scores[i]=scores[i]-1;
       }
   }

   Arr operator+(Arr o2)
   {
       for(int i=0;i<5;i++)
       {
           o2.scores[i]=o2.scores[i]+5;
       }
       return o2;
   }

   void print()
   {
       for(int i=0;i<5;i++)
       {
           cout<<scores[i]<<endl;
       }
   }
};

void main()
{
   Arr o,o1,o3;

   o.print();
   o++;
   o.print();
   o--;
   o.print();
   o3=o+o1;
   o3.print();
   system("pause");
}
