Questions tagged [construction]

Use for questions related to building a data structure, such as a heap.

Construction is a concept of Object-Oriented languages.

Objects need to be setup for use:

  • Their member variables need to be allocated
  • Any Object member variables also need to be constructed
  • The Object methods need to be setup for calling

This process is accomplished by construction.
