Chapter 7. Dynamic Memory Allocation

In the previous chapter, we talked about class definitions and how to devise your own custom class. We discussed how by devising our own custom classes, we can construct variables that represented entities within your game or program.

In this chapter, we will talk about dynamic memory allocations and how to create space in memory for groups of objects.

Assume that we have a simplified version of class Player, as before, with only a constructor and a destructor:

class Player
{
  string name;
  int hp;
public:
  Player(){ cout << "Player born" << endl; }
