A pointer is a variable that stores the memory address of another variable

Pointers continuation. Maps in C++ are a very useful data structure for storing key-value pairs You will want to be careful storing pointers, but unlike a vector, once inserted into a map objects don't move around even if other elements are added or removed, however, storing pointers is good, especially if you're working with lots of textures or other large data objects.
