C++ Program for Stack Operations Using Arrays

Write a C++ Menu Driven Program for Stack Operations Using Arrays. Here’s a Simple Program for Stack Operations Using Classes in C++ Programming Language.

What is Stack?

• Stack is a LIFO (last in first out) structure. It is an ordered list of the same type of elements. A stack is a linear list where all insertions and deletions are permitted only at one end of the list.

• When elements are added to stack it grow at one end. Similarly, when elements are deleted from a stack, it shrinks at the same end.

• It involves various operations such as push,pop,stack empty,stack full and display.

Below is the source code for C++ Menu Driven Program for Stack Operations Using Arrays which is successfully compiled and run on Windows System to produce desired output as shown below :
