Defining an object without calling its constructor in C++

Store a pointer to an Object rather than an actual Object

thus:

class Program
{
public:
   Object* myObject; // Will not try to call the constructor or do any initializing
   Program()
   {
      //Do initialization
      myObject = new Object(...);  // Initialised now
   }

}

Don’t forget to delete it in the destructor. Modern C++ helps you there, in that you could use an auto_ptr shared_ptr rather than a raw memory pointer.
