The top of a stack implemented as a linked list is the head of the list. All insertions and extractions occur at the head thus a forward list (singly-linked list) is sufficient to implement a stack.

How does a linked list differ from stack and queue?
A linked list is a data structure that allows bi-directional traversal with constant-time access to both the head and the tail of the list. Elements may be pushed and popped from anywhere in the list. A stack is a structure where elements are pushed and popped only at the head of the stack. A stack is typically implemented using an array (either fixed-length or variable-length) where elements are pushed and popped from the end of the array (you need to keep track of where the last-used element is). However, a stack can also be implemented as a singly-linked list, pushing and popping at the head of the list. Stacks generally do not allow traversal of the elements.
Why is the constructor of the Stack Linked List class empty?
The default constructor of a stack is empty because the default value of any container, including a linked list, is an empty container which requires no arguments (all members default to zero).
Why stack is implemented by link list?
A Linked-List is basically a series of Nodes. Each Node contains two things: The contents, and the pointer to the next Node in the Linked-List. So you can traverse the Linked-List by following the "next" pointers in each Node, a bit like following road directions from city to city. A stack is an abstract data type where you have two operations: "push" and "pop". Pushing means to put an item in the stack, Popping means to get the first element of the stack. When you push an item onto a stack, you put the item at the top: so its like cutting in line to the very front. The last one in is now first, and thus, the first one out. Another helpful image is a "stack" of trays at a cafeteria -- you can only get the tray from the top of the stack, or put a tray on top of the stack. The very first tray in the stack is actually the one at the very bottom, and thus, the last one to be used. "First in, Last Out." A stack deals with what comes first/last, while a Linked-List describes how data is stored. A stack needs to store data, so a stack can be implemented as a Linked-List.
How do you copy all the elements from a given stack implemented in a linked list to a new one and returns the pointer to the new stack?
LIFO
What is the Data structures used for stack?
A stack is a linear last-in first-out list type data structure. Several implementations are possible. Two examples are the array and the linked list. The array is quick, but is limited in size. The linked list requires overhead to allocate, link, unlink, and deallocate, but (except for total available memory) is not limited in size. One compromise might be a linked list of arrays. Another compromise might be to not necessarily unlink and delete when an element is popped off the stack.
Where linked list using?
linked list are used for creation of stack,queues to use memory in optimum manner linked list are used as they are dynamic in nature
Is it possible to implement stack and queues using linkes list?
Yes it is possible to implement stack and queue using linked list

How do you copy all the elements from a given stack implemented in a linked list to a new one and returns the pointer to the new stack?
LIFO
What are the the two ways in representing the stack?
one-dimensional array, and doubly-linked list.
What are advantages of stack?
some disadvantages created in stack using array then that problem solve to linked list use in stack.First advantage for size of stack not limited in linked list using.second essay to stack programme implement using only one pointer.

How do you implement stack without array?
Stacks are often implemented using the same node structure as a linked list.
Why you use linked list instead of arrays?
You would use linked lists instead of arrays in two instances: 1) You don't know how long your list will be and it is apt to dramatically change length. 2) You will make lots of additions and removals in the middle of your list.
Which data structure is Best for library management system wheater Tree or Linked list?
It depends on what you intend to do with the data. The assumption is the data is dynamic, the number of elements are not known in advance. Binary trees are best if you want to sort the data as it is entered. Linked lists are best if you simply want a list of sequential data, or need to implement a stack or a queue.
