Chapter 4, Problem 7E
Program Plan Intro
Stack:
Stack is a container in which elements inserted and removed in LIFO (Last In First Out) manner.
- The “top” is address of top element of stack.
- Basic stack operations are given below:
- push(): Insert an object into stack top.
- pop(): Delete object in stack top.
- topEl(): Get object in stack top.
- isEmpty(): Check stack is empty or not.
Queue:
- Queue is another data structure in which insertion and removal of elements are in FIFO(First In First Out) manner.
- Basic operations are given below:
- Enqueue(): Insert an element into back of queue
- Dequeue(): Remove an item from front of queue
- front(): Get first element of queue without removal of it.
- isEmpty(): Check queue is empty or not.

1 Implement a Queue Data Structure specifically to store integer data using a Singly Linked List.
2 The data members should be private.
3
You need to implement the following public functions:
4
1. Constructor:
5 It initialises the data members as required.
6
7
8
2. enqueue(data) :
This function should take one argument of type integer. It enqueues the element into the queue and returns nothing.
3. dequeue():
It dequeues/removes the element from the front of the queue and in turn, returns the element being dequeued or removed. In case the queue is empty, it r
4. front ():
10
11 It returns the element being kept at the front of the queue. In case the queue is empty, it returns -1.
12 5. getSize():
13
It returns the size of the queue at any given instance of time.
14 6. 1sEmpty():
15
It returns a boolean value indicating whether the queue is empty or not.
16 Operations Performed on the Stack:
17 Query-1 (Denoted by an integer 1): Enqueues an integer data to the queue.

Your Stack should not be of the fixed sized. It should be able to grow itself. So using the class made in task 1, make a class named as Stack, having following additional functionalities: bool empty() : Returns whether the Stack is empty or not. Time Complexity should be: O(1) bool full() : Returns whether the Stack is full or not. Time Complexity should be: O(1)int size() : Returns the current size of the Stack. Time Complexity should be: O(1)Type top () : Returns the last element of the Stack. Time Complexity should be: O(1) void push(Type) : Adds the element of type Type at the top of the stack. Time Complexity should be: O(1) Type pop() : Deletes the top most element of the stack and returns it. Time Complexity should be: O(1) Write non-parameterized constructor for the above class.
