You'll need to use a doubly-linked circular list, since otherwise when you pop off the tail element you'll need to whizz all the way round the list to find its predecessor.
See the links section for an implementation of a doubly-linked circular list.

Program to delete elements at both ends in a dequeue using c plus plus?
#include<deque> std::deque<int> deq; deq.push_back (42); deq.pop_back (); deq.push_front (0); deq.pop_front ();
How do you write a program to delete elements at both ends of a deque using C plus plus?
The C++ STL (Standard Template Library) provides a std::deque template specifically for this purpose: std::deque<int> deq {}; // default construct an empty deque of type int deq.push_back (42); // deq = {42} deq.push_front (0); // deq = {0, 42} deq.push_back (100); // deq = {0, 42, 100} deq.pop_front (); // deq = {42, 100} deq.pop_back (); // deq = {42} As with all other STL containers, any type or class that can be copy or move constructed can be placed in a std::deque, including other STL containers (even std::deque itself).
What are types of Queue?
Queue is a data structure which is based on FIFO that is first in first out. Following are the types of queue: Linear queue Circular queue Priority queue Double ended queue ( or deque )
What is difference between enque and dequeue?
deque

What do you understand by deque?
A double ended queue (or deque ) is a queue where insertion and deletion can be performed at both end that is front pointer can be used for insertion (apart from its usual operation i.e. deletion) and rear pointer can be used for deletion (apart from its usual operation i.e. insertion)
What is the need of deque?
A double ended queue (or deque ) is a queue where insertion and deletion can be performed at both end that is front pointer can be used for insertion (apart from its usual operation i.e. deletion) and rear pointer can be used for deletion (apart from its usual operation i.e. insertion). So when we need to insert or delete at both end we need deque.
Which data structure allows deletion from both ends and insertion only from one end?
Deque double ended queue
What has the author Nicolaus written?

A program for queue ADT by using arrays in c plus plus?
Arrays are not suitable for implementing queues because while they are ideal for adding to the end, the are not ideal for extraction from the beginning. For that you need a deque. Regardless, the STL (standard template library) already provides an efficient queue ADT in std::queue.
