What are the different container choices in C++11?

What are the different container choices in C++11?

In C++11, you have several container choices including vector, list, deque, set, map, unordered_set, and unordered_map.

Can you explain the differences between vector and 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 unordered_map instead of map?

Use unordered_map when you need faster average-case lookups and don't require the elements to be sorted. It's based on hash tables.

What are the advantages of using set over vector?

A set automatically handles duplicates and keeps elements sorted, while a vector allows duplicates and does not maintain order.
