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.

Renaming intrinsic types with typedef

We have already looked at some of C's basic data typeswhole numbers (integers), real numbers (floating point and complex numbers), characters, enumerations, and Boolean values. We called them intrinsic data types since they are built into the language and are always available. By referring to these types specifically as data types, we give focus to the content of variables of those types—containers of data that can be manipulated. However, the use of the term data type is not strictly accurate. In reality, these types are classified in C as arithmetic types. C has other types, some which we have encountered—function types, structure types, and void types—and some of which we have not yet encountered—array types, pointer types, and union types. We will explore array types and pointer types in greater detail in later chapters.

For all of these types, C provides a way to rename them. This is for...
