vectors and push_back
Author
Ok, lets say I have a vector
vector<MyClass> myVec;
When I call:
myVec.push_back(Object); //assume Object is of type MyClass
is Object passed by reference or is a copy of Object placed in the vector?

That''s why you normally should use a vector of (smart) pointers if you''re going to use it with objects.
It places a copy of the object in the vector--it''s the only exception-safe way to do it. Overload your copy constructor to output a message and you will see it called when you push_back.
