Overview of this book

The foundation for many modern programming languages such as C++, C#, JavaScript, and Go, C is widely used as a system programming language as well as for embedded systems and high-performance computing. With this book, you'll be able to get up to speed with C in no time. The book takes you through basic programming concepts and shows you how to implement them in the C programming language. Throughout the book, you’ll create and run programs that demonstrate essential C concepts, such as program structure with functions, control structures such as loops and conditional statements, and complex data structures. As you make progress, you’ll get to grips with in-code documentation, testing, and validation methods. This new edition expands upon the use of enumerations, arrays, and additional C features, and provides two working programs based on the code used in the book. What's more, this book uses the method of intentional failure, where you'll develop a working program and then purposely break it to see what happens, thereby learning how to recognize possible mistakes when they happen. By the end of this C programming book, you’ll have developed basic programming skills in C that can be easily applied to other programming languages and have gained a solid foundation for you to build on as a programmer.

Introducing enumerations

There are times when we want a program or function variable to take an integer value that is from a set of related values. For convenience, and to make the relationship between each value clear, each value in the set of values is given a name. We can think of this set as a grouping of conceptually related values.

Let's say we want a variable to represent the suits of a deck of cards. Naturally, we know each suit by its name – spades, hearts, clubs, and diamonds. But C doesn't know about card names or card suits. If we wanted to represent each of these suits with a value, we could pick any value for each, say, 4 for spades, 3 for hearts, 2 for diamonds, and 1 for clubs. Our program, using this simple scheme, might look as follows:

int card;
...
card = 3; // Heart.

But we would have to do the work of remembering the conceptual relationship. We would have to do the work remembering which value corresponds to which suit. This is...
