c++ Copy Constructor Conventions

A couple of very simple to follow rules for copy constructors.
Case A: An object has no dynamically allocated pointers. Let the default copy constructor do the work and don't bother writing one.

Case B: If said object does contain dynamic pointers, then you'll need to write your own copy constructor as follows.

MyObject(const MyObject& o) {
   // Do some stuff for a true deep copy
   // Make new pointers and stuff :)
}
