[Dev-C++] STL stack/vector pushing class objects

[Matt K. <sy...@as...>]

This may seem trivial, but I'm having troubling finding a clear answer 
through just searching on the net.

My question is:
In the following scenario where you are using STL stack or vector 
container with a class object, ie:

stack<board> moves;

if you do something like:

moves.push( thismove );

Does thismove get copied or is it passed into the stack by reference?

In other words, if I am dynamically allocating thismove, should I be 
worrying about deallocating (freeing) it at a later point? Or does pop() 
call the deconstructor on the object for you?

Thank you!
