First, a vector is a template class but not the array is.
So obviously there are members to access the elements of
the vector like, range checking, iterators,
insertion/deletion, predicates, etc.

Since it is a template class, the same implementation can
be used for any type including pointers, objects/user
defined types.

Second, as said by others, vector automatically grow as we
invoke push_back(), we can reserve additional space for
elements, etc.

Distinguish between a # include and #define.
