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.

Simplifying the use of struct types with typedef

All of the considerations we explored for enums equallyapply tostructs.We will go through each of them as they apply to structs.

Before we examine the use of typedef with structs, we must first complete the picture of using structs. In the last chapter, Chapter 9, Creating and Using Structures, we used structs by first defining them and then separately declaring variables of that type, as follows:

  // First define a structured type.

struct Card { Face face; Suit suit; ... };

// Then declare variables of that type.

struct Card c1 , c2 , c3 , c4 , c5;

In the preceding code fragment, we have defined one type,struct Card. In a separate statement, five variables of that type are declared—c1,c2,c3, c4, andc5.

Another way to achieve the same result is to both define the structured type and declare variables of that type in one statement, as follows:

// Defining an structure and declaring...
