How to implement stack and queue using linked list?

Please visit my earlier article on Linked List implementation in C# to get a basic understanding of Linked List. Implementing Stack functionalities using Linked List Implementing Queue functionalities using Linked List. What is Stack? A Stack is a linear data structure which allows adding and removing of elements in a particular order.

How to use linked list in a C + + program?

C++ Program to Implement Stack using linked list 1 Push – This adds a data value to the top of the stack. 2 Pop – This removes the data value on top of the stack. 3 Peek – This returns the top data value of the stack.

Which is an application of a linked list?

Applications of linked list data structure. A linked list is a linear data structure, in which the elements are not stored at contiguous memory locations. The elements in a linked list are linked using pointers as shown in the below image: Applications of linked list in computer science –. Implementation of stacks and queues.

How to create a linked list based stack?

When you run the program, enter the number of nodes required for linked-list based stack. Then start entering value to the top of the stack. In the following figure, 434 is the last in entry, so it is the top of the stack, also head of the linked-list.

How to peek item from stack using linked list?

1 internal void Pop () 2 if (top == null) 3 Console.WriteLine (“Stack Underflow. Deletion not possible”); 4 return; 5 Console.WriteLine (“Item popped is {0}”, top.data); 6 top = top.next; 7 } Peek the element from Stack.

What do we learn from using linked lists?

We will be learning about: What a stack is. Implementing stack functionalities using linked lists. Uses of stacks. What a queue is. Implementing queue functionalities using linked lists. Uses of queues. Before proceeding further, I would recommend downloading the source code from GitHub.

What is the difference between a stack and a queue?

Stack is basically a data structure that follows LIFO (LAST IN FIRST OUT). Queue is one which follows FIFO (FIRST IN FIRST OUT). In general, Stacks and Queues can be implemented using Arrays and Linked Lists.
