Practical C Programming

By: B. M. Harwani

Overview of this book

Used in everything from microcontrollers to operating systems, C is a popular programming language among developers because of its flexibility and versatility. This book helps you get hands-on with various tasks, covering the fundamental as well as complex C programming concepts that are essential for making real-life applications. You’ll start with recipes for arrays, strings, user-defined functions, and pre-processing directives. Once you’re familiar with the basic features, you’ll gradually move on to learning pointers, file handling, concurrency, networking, and inter-process communication (IPC). The book then illustrates how to carry out searching and arrange data using different sorting techniques, before demonstrating the implementation of data structures such as stacks and queues. Later, you’ll learn interesting programming features such as using graphics for drawing and animation, and the application of general-purpose utilities. Finally, the book will take you through advanced concepts such as low-level programming, embedded software, IoT, and security in coding, as well as techniques for improving code performance. By the end of this book, you'll have a clear understanding of C programming, and have the skills you need to develop robust apps.

Implementing a stack using a singly linked list

In this recipe, we will learn how to implement a stack that has a LIFO structure. LIFO means that whatever element was added to the stack last will be the first to be removed. The stack is a very important component of any compiler and operating system. The stack is used in branching operations, recursion, and many other system-level tasks. The stack can be implemented using arrays as well as through linked lists. In this recipe, we will learn how to implement a stack using a single linked list.

How to do it...

Follow these steps to implement a stack using a linked list:

  1. A structure is defined called node. In this structure, besides a data member for storing content for the...
