Pointers to Class Members

 

#include <iostream>
using namespace std;
class MyClass {
public:
  MyClass(int i) { 
     val=i; 
  }
  int val;
  int doubleValue() { 
     return val+val; 
  }
};
int main()
{
  int MyClass::*data;                                 
  int (MyClass::*func)();                             
  MyClass myObject1(1), myObject2(2);                 
  data = &MyClass::val;                               
  func = &MyClass::doubleValue;
  cout << "Here are values: ";
  cout << myObject1.*data << " " << myObject2.*data << "\n";
  cout << "Here they are doubled: ";
  cout << (myObject1.*func)() << " ";
  cout << (myObject2.*func)() << "\n";
  return 0;
