#include <iostream.h> 
#include<conio.h> 
class myclass 
{ 
          int i; 
          public: 
                 void read(int j) 
              { 
                     i= j; 
              } 
                 int getint() 
           {     
                     return i; 
           } 
}; 
              void main() 
           { 
               clrscr(); 
               myclass ob, *objectPointer; 
               objectPointer = &ob; // get address of ob 
               objectPointer->read(10); 
               cout<<objectPointer->getint();       // use -> to call getlnt() 
               getch(); 
          } 
Output:
