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(); 
           }
