Write a C++ program for definition of operator+ ():

#include <iostream.h> 
 #include<conio.h> 
 class Values 
 { 
                   int a,b; 
           public: 
                   Values() {} 
                   Values(int aa, int bb) 
                     { 
                            a=aa; 
                        b=bb; 
                     } 
                        void show() 
                    { 
                        cout <<a <<" "; 
                        cout <<b <<"\n"; 
                     } 
                        Values operator + (Values p); 
 }; 
                       Values Values :: operator + (Values p) 
                    { 
                          Values temp; 
                          temp.a =p.a +a; 
                          temp.b =p.b +b; 
                          return temp; 
                     } 
                         void main() 
                    { 
                        clrscr(); 
                        Values v1(20,30),v2(15,40); 
                        v1.show(); 
                        v2.show(); 
                        v1 =v1 +v2; 
                        v1.show(); 
                        getch();
