Stack With Implementation Using Linked List and Array in C++
A stack is an Abstract Data Type (ADT) that is extensively used in most programming languages. It is termed stack because it behaves like a real-world stack, such as a deck of cards or a pile of dishes.
A real-world stack can only perform operations at one end. For instance, we can only add or take a card or plate from the top of the stack. Similarly, Stack ADT permits all data operations at only one end. We can only access the top element of a stack at any given time.
This property makes it a LIFO data structure. LIFO is an abbreviation for Last-in-First-Out. In this case, the element that was placed (inserted or added) last is accessed first. In stack terminology, an insertion operation is referred to as a PUSH operation, and a removal activity is referred to as a POP operation.
