What are the standard collections in C++11?

Can you explain the standard collections introduced in C++11?

Sure! C++11 introduced several standard collections, including vectors, lists, sets, and maps. Each has its own use cases.

What is the difference between a vector and a list?

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, while a vector is better for ordered collections.

Can you give an example of using a map?

Certainly! A map stores key-value pairs. For example, you can use it to count occurrences of words in a text.
