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 binary number into a decimal using a bitwise operator

In this recipe, you will learn how to convert a binary number into a decimal.

How to do it…

To convert a binary number into a decimal, perform the following steps:

  1. Enter a binary number.
  2. Apply a mod 10 (% 10) operator to the binary digits of the binary number to isolate the last bit of the binary number.
  3. Left-shift the binary digit isolated in step 2 to multiply it by the power of 2. 
  4. Add the product of the previous multiplication to the variable that will store the result, that is, the decimal number. Let's call the variable dec.
  5. The last digit of the binary number is truncated.
  6. Repeat step 2 to step 4 until...
