Defining an object without calling its constructor in C++

In C++, I want to define an object as a member of a class like this:

Object myObject;

However doing this will try to call it's parameterless constructor, which doesn't exist. However I need the constructor to be called after the containing class has done some initialising. Something like this.

class Program
{
public:
   Object myObject; //Should not try to call the constructor or do any initializing
   Program()
   {
      ...

      //Now call the constructor
      myObject = Object(...);
   }

}
