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.

Converting a decimal into binary using a bitwise operator

In this recipe, we will learn to convert a decimal number into a binary number by making use of a bitwise operator. Bitwise operators operate on the binary digits of a number and enable us to do precise manipulation as desired.

How to do it…

To convert a decimal number into a binary number by making use of a bitwise operator, perform the following steps:

  1. Enter a decimal number. This number is internally stored in the form of binary digits.
  2. Isolate the least significant bit of the decimal number by applying a logical AND operation between the entered decimal number and value 1.
  3. The least significant bit that results from step 2 is stored in an array...
