Write a C++ program for friend operator.

#include <iostream.h>


#include<conio.h>


class Num


{


       friend Num operator+(Num ob, int i);


       friend Num operator+(int i, Num ob);


       int count;


       public:


                     Num(int cc=0)


              {


                     count=cc;


               }


                     Num& operator=(int i);


                     void Show()


              {


                     cout<<count<<endl;


               }


 };


                     Num& Num::operator=(int i)


              {


                     count=i;


                     return *this;


               }


                     Num operator+(Num ob, int i) // This handles ob+int.


              {


                     Num temp;


                     temp.count=ob.count+i;


                     return temp;


               }


                     Num operator+(int i, Num ob) // This handles int+ob ..


               {


                     Num temp;


                     temp.count=ob.count+i;


                     return temp;


               }


                     void main()


               {


                     clrscr();


                     Num obj;


                     obj=10;


                     obj.Show();


                     obj=10+obj;


                     obj.Show();


                     obj=obj+ 12;


                     obj.Show();


                     getch();


               }


Output:


10
