Queue and List Operations

Objective:

Write a C++ program to manage a queue and a list through a menu-driven interface. The program should allow users to perform various operations on both the queue and the list as specified in the given menu options. Task Description:

Your program should implement the following functionalities:

Queue Operations:
    Enter a specified number of elements into the queue.
    Dequeue (remove) the front element of the queue.
    Check if the queue is empty. If not, print the elements of the queue.

List Operations:
    Enter a specified number of elements into the list.
    Remove the last element from the list.
    Print the elements of the list using an iterator.
