What a stack is

What a stack is

Array-based stack with items A, B, C, a topPointer arrow, and examples of push, pop, peek, empty and full conditions

A stack is a data structure where items are added and removed from the same end, called the top. It follows last in, first out, or LIFO, so the most recently added item is the first one removed.
