A stack is a common data structure used in many applications. It is an abstract data type defined not by its data type, but by its operations.
Stack operations are critical to its implementation. We will create a C++ stack using linked-list in this article.
This program demonstrates the implementation of a stack and its operations using simple functions and the program is compiled using Dev-C++ compiler 184.108.40.206 installed on windows 7 64-bit computer.
In this article, you will find the following sections – problem definition, flowchart, program source code and verified output to help you learn to programme effectively. Since the level of the program is difficult, it is for intermediate level learners of C programming language.
A stack is a linear data structure with a predefined size. It is possible to increase or decrease the stack size, but that depends on the application using the stack data structure.
To build a stack data structure, you can use two methods – an array or a linked -list. A fixed size array can work as an array for a simple data type, however, for a stack that uses dynamic memory allocation, we need a linked-list.
A stack works in a specific way called the LIFO principle –Last in, First out. The last item inserted onto the stack is processed first because items are inserted from the top of the stack and removed from the top first. The stack operations implemented in this program are
