What are the different types of C++ STL containers?

C++ STL provides several container types, including vectors, lists, deques, sets, maps, and more. Each serves different purposes.

Can you explain the differences between vectors and lists?

Sure! Vectors are dynamic arrays that allow random access and are efficient for adding/removing elements at the end. Lists are doubly linked lists, which allow efficient insertions and deletions from anywhere but do not support random access.

When should I use a map instead of a set?

Use a map when you need to associate keys with values, while a set is used for storing unique elements without any associated values.

What about unordered containers?

Unordered containers, like unordered_map and unordered_set, use hash tables for storage, providing average constant time complexity for lookups, insertions, and deletions.
