How is stack and queue implemented in C++?
A queue is a FIFO (First In First Out), while a stack is a LIFO (Last In First Out) data structure. A stack pushes a new element to the top of the stack and also pops the element at the top. A queue, however, dequeues (removes) an element from the top of the queue, but it enqueues (inserts) an element at the bottom.
What is mean by stack in C programming?
A stack is a linear data structure, collection of items of the same type. Stack follows the Last In First Out (LIFO) fashion wherein the last element entered is the first one to be popped out.
Can queue be implemented using stack?
A queue can be implemented using two stacks.
What is stack and queue in Java?
A queue is a lot like a stack. … Queues are open from both ends: one end for inserting data ( enqueue ), and the other end for removing data ( dequeue ). A stack is only open from one end. Simplied: for a stack we remove the most recently added element, but for a queue, we remove the “oldest” element.
How do you code a queue in C++?

What is the difference between stack and queue?
Stack and Queue both are the non-primitive data structures. The main differences between stack and queue are that stack uses LIFO (last in first out) method to access and add data elements whereas Queue uses FIFO (First in first out) method to access and add data elements.
What is queue and stack?
Stack is a container of objects that are inserted and removed according to the last-in first-out (LIFO) principle. Queue is a container of objects (a linear collection) that are inserted and removed according to the first-in first-out (FIFO) principle.
