What are the key features of C++ STL data structures?

C++ STL data structures include vectors, lists, sets, and maps, each offering unique features like dynamic sizing and efficient searching.

Can you explain the difference between a vector and a list?

Sure! A vector is a dynamic array that allows random access, while a list is a doubly linked list that allows efficient insertions and deletions.

When should I use a set instead of a vector?

Use a set when you need to store unique elements and require fast lookups, as it automatically handles duplicates.

What are the advantages of using maps in C++?

Maps store key-value pairs and provide fast retrieval based on keys, making them ideal for associative data.
