Write a C++ program to increment time variable with ++operator.

#include <iostream.h> 
 #include<conio.h> 
 class Timer 
 { 
     private: 
                  unsigned int time; 
     public: 
                  Timer():time(0) {} 
                  int get_time() 
                     { 
                        return time; 
                     } 
                  void operator ++() 
                    { 
                       ++time; 
                    } 
  }; 
    void main() 
 { 
   clrscr(); 
   Timer t1 ,t2; 
   cout <<"\nt1 = " <<t1.get_time(); 
   cout <<"\nt2 = " <<t2.get_time(); 
  ++t1; 
  ++t2; 
  ++t2; 
   cout <<"\nt1 = " <<t1.get_time(); 
   cout <<"\nt2 = "<<t2.get_time()<<endl; 
   getch(); 
 }
