Introduction of STL #3: Associative Containers



Why STD set is associative container?

So what makes it associative? The fact that elements in a set are referenced by their key and not by their absolute position in the container. The key, of course, is the element itself. Think of it as a map where the keys are values are equal and given that, where the duplicate copy of the same content is eliminated.

What are sequence containers derived containers and associative containers?

Sequence containers implement data structures that can be accessed sequentially. Associative containers implement sorted data structures that can be quickly searched (O(log n) complexity). Map: Collection of key-value pairs, sorted by keys, keys are unique (class template).

Is a map a container?

std::map is a sorted associative container that contains key-value pairs with unique keys. Keys are sorted by using the comparison function Compare . Search, removal, and insertion operations have logarithmic complexity. Maps are usually implemented as red-black trees.
