C++ Containers

The C++ Containers (vectors, lists, etc.) are generic vessels capable of holding many different types of data. For example, the following statement creates a vector of integers:
vector<int> v;
Containers can hold standard objects (like the int in the above example) as well as custom objects, as long as the objects in the container meet a few requirements: When describing the functions associated with these various containers, this website defines the word TYPE to be the object type that the container holds. For example, in the above statement, TYPE would be int.
