What are the different types of collections in C++?

In C++, the main types of collections are arrays, vectors, lists, sets, and maps. Would you like to know more about any specific type?

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

Sure! A vector is a dynamic array that allows random access and is stored in contiguous memory, while a list is a doubly linked list that allows efficient insertions and deletions but does not support random access.

When should I use a set instead of a vector?

You should use a set when you need to store unique elements and perform operations like union, intersection, or difference efficiently. A vector is better for ordered collections where duplicates are allowed.

What about maps? How do they work?

Maps in C++ are associative containers that store key-value pairs. They allow fast retrieval of values based on their keys, and they automatically sort the keys.
