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 limits and dangers of the preprocessor

The preprocessor is a simple macro processor that processes the source text of a C program before the program is read by the compiler. It is controlled via single-line preprocessor directives and transforms the original source text by interpreting macros embedded in the original source text to substitute, add, or remove text based on the given directives. The resulting preprocessed source text must then be a valid C program.

The following table provides an overview of the basic preprocessor directives:

#include Insert text from another source file.
#define Add a preprocessor macro definition.
#undef Remove a preprocessor macro definition.
