TOPICS (not an exhaustive list)

* structures - name and purpose of an aggregate construct
  structure variables, member variables, assigning structures
  passing structure as a parameter, complex structures, arrays
  of structures, arrays as member variables of a structure

* classes - purpose, advantages over structures, public/private
  members, inline/outside function definition, mutators/accessors,
  constructors, constructor overloading and default constructor,
  friend functions, static constants

* pointers - definition and usage, pointers and constants, array names
  and pointers, null/loose pointer, pointers to objects (arrow
  operator), pointer arithmetic, passing pointers by value and by
  reference, returning pointers

* dynamic memory allocation - static/dynamic/automatic variables,
  allocation for basic types, for arrays, for objects, allocation of
  objects with dynamic members: the big three (destructor, copy
  constructor, assignment overloading); memory leak problem for
  assignment overloading, protection against self-assignment,
  implementing stackability

* vectors - advantages over (raw) arrays, declaring, adding/removing
  element, comparing/assigning vectors, passing by value/reference
  returning, iterators, iterator arithmetic, using iterators
  to insert, erase elements, sort vector
