How to release std::vector if there is no heap memory

Question

I have a class member variable like this:

vector >  m_stacks;

When I populate it, I do like this:

v         


        

Answer 1

You don't have to do anything for m_stacks (a class data member). Acquired memory will be released automatically when the class destructor will be called. This is the purpose for which std::vector is used.
