Deque in C++ Example | C++ Deque Program is today’s topic. Deque stands for a double-ended queue. It is pronounced as “deck”. It is containers that have dynamic sizes and can be expanded or contracted on both the ends, i.e., both the ends are operational in this deque.  Vectors also have contiguous storage allocation, but in the case of the deque, memory is generally dynamically allocated.

Deque in C++ Example

Deque is a data structure that is implemented on the double-ended queue. It is related to queue as in queue insertion is done at the end, and deletion is done from the front. Double-ended queues are individual queues in which insertion and deletion are possible at both ends.

The std::deque(double-ended queue) is an indexed sequence container that allows fast insertion and deletion at both its beginning and its end. In addition, insertion and deletion at either end of a deque never invalidate pointers or references to the rest of the elements.
