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.

Defining enumerations

The enumeration type allows us to specify a set, or group, of values a variable may have, and only those values. Any assignment of a value outside of that range/group would be a compiler error. The compiler catching such an error rather than it being caught at runtime is preferred since it prevents unexpected program crashes.

The syntax for defining an enumerated type is as follows:

enum name { enumeration1, enumeration2, … , enumerationN };

The type consists of the two words, enum and name. The group of enumerated items is contained within { and }. Each named item in the group of enumerated items is separated by , and the definition is concluded with ;.

So, the definition of our enumerated type of suit would be as follows:

enum suit { spade , heart , diamond , club };

Or, we might want to make each item stand on its own, as follows:

enum suit { 
spade ,
heart ,
diamond ,
