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.

Performing postorder traversal of a binary tree non-recursively

In this recipe, we will perform postorder traversal of a binary tree without recursion. This will be done through non-recursive calls to the function.

Getting started

To create a binary tree, refer to the Creating a binary search tree and performing an inorder traversal on it recursively recipe. We will be performing postorder traversal on the same binary tree we created in this recipe.

How to do it...

For postorder traversal of a binary tree, we need to apply three tasks—L, R, and V—on each...
