std::list is a container that supports constant time insertion and removal of elements from anywhere in the container. … It is usually implemented as a doubly-linked list. Compared to std::forward_list this container provides bidirectional iteration capability while being less space efficient.
How does STD list work?
The std::list is implemented as a doubly-linked list. This means list data can be accessed bi-directionally and sequentially. The Standard Template Library list doesn’t support fast random access, but it supports sequential access from all directions. You can scatter list elements in different memory chunks.
What is the difference between std :: list and std :: vector?
In vector, each element only requires the space for itself only. In list, each element requires extra space for the node which holds the element, including pointers to the next and previous elements in the list. … List is not thread safe. Deletion at the end of the vector needs constant time but for the rest it is O(n).
