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.

Managing Strings

Strings are nothing but arrays that store characters. Since strings are character arrays, they utilize less memory and lead to efficient object code, making programs run faster. Just like numerical arrays, strings are zero-based, that is, the first character is stored at index location 0. In C, strings are terminated by a null character, \0.

The recipes in this chapter will enhance your understanding of strings and will acquaint you with string manipulation. Strings play a major role in almost all applications. You will learn how to search strings (which is a very common task), replace a string with another string, search for a string that contains a specific pattern, and more. 

In this chapter, you will learn how to create the following recipes using strings: 

  • Determining whether the string is a palindrome 
  • Finding the occurrence...
