Learn C Programming

By: Jeff Szuhay

Overview of this book

C is a powerful general-purpose programming language that is excellent for beginners to learn. This book will introduce you to computer programming and software development using C. If you're an experienced developer, this book will help you to become familiar with the C programming language. This C programming book takes you through basic programming concepts and shows you how to implement them in C. Throughout the book, you'll create and run programs that make use of one or more C concepts, such as program structure with functions, data types, and conditional statements. You'll also see how to use looping and iteration, arrays, pointers, and strings. As you make progress, you'll cover code documentation, testing and validation methods, basic input/output, and how to write complete programs in C. By the end of the book, you'll have developed basic programming skills in C, that you can apply to other programming languages and will develop a solid foundation for you to advance as a programmer.

Understanding the program development cycle

There are two main types of development environments:

  • Interpreted: In an interpreted environment such as Python or Ruby, the program can be entered line by line and run at any point. Each line is evaluated and executed as it's entered and the results are immediately returned to the console. Interpreted environments are dynamic because they provide immediate feedback and are useful for the rapid exploration of algorithms and program features. Programs entered here tend to require the interpreting environment to be running as well.
  • Compiled: In a compiled environment such as C, C++, C#, or Objective-C, programs are entered into one or more files, then compiled all at once, and if no errors are found, the program can be run as a whole. Each of these phases is distinct, with separate programs used for each phase. Compiled programs tend to execute faster since there is a separate, full compilation phase, and can be run independently of the interpreting environment.

As with shampoo, where we are accustomed to wet hair, lather, rinse, and repeat, we will do the same with C – we will become familiar with the edit, compile, run, verify, and repeat cycle.
