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 multiple tasks with multiple threads

In this recipe, you will learn how to multitask by executing two threads in parallel. Both of the threads will do their tasks independently. As the two threads will not be sharing a resource, there will not be a situation of race condition or ambiguity. The CPU will execute any thread randomly at a time, but finally, both of the threads will finish the assigned task. The task that the two threads will perform is displaying the sequence of numbers from 1 to 5.

How to do it…

  1. Define two variables of the type pthread_t to store two thread identifiers:
pthread_t tid1, tid2;
  1. Invoke the pthread_create function twice to create two threads, and assign the identifiers that we...
