c++ deleting vector class member memory in destructor

Question

I have a class containing a vector member variable. I know that vectors stored on the stack will be cleaned up (i.e. memory free\'d) when they go out of scope, but I\'m not

Answer 1

The vector is cleaned up for you already! When a class gets destructed all of it's members destructors are also called. In this case v's destructor is called, which cleans up whatever it allocated.

Non-static members' dtors are called when you reach the closing } of the destructor in the reverse order they were declared in. Then your base class destructor is called, if present.
