Beginning C, Fifth Edition

Book Description

Beginning C, 5th Edition teaches you how to program using the widely-available C language. You'll begin from first-principles and progress through step-by-step examples to become a competent, C-language programmer. All you need are this book and any of the widely available free or commercial C or C++ compilers, and you'll soon be writing real C programs.

C is a foundational language that every programmer ought to know. C is the basis for C# used in Microsoft .NET programming. It is the basis for Objective-C used in programming for the iPhone, the iPad, and other Apple devices. It is the basis for the C++ that is widely used in a great many contexts, including the GNU Project. It underlies the Linux operating system and many of its utilities. Learning C provides a strong foundation for any programming care, and will even help you better understand more modern languages such as Java.

Beginning C is written by renowned author Ivor Horton. The book increases your programming expertise by guiding you through the development of fully working C applications that use what you've learned in a practical context. You'll also be able to strike out on your own by trying the exercises included at the end of each chapter. At the end of the book you'll be confident in your skills with all facets of the widely-used and powerful C language.

  • The only beginning-level book to cover the latest ANSI standard in C

  • Revised to cover C99 features newly-supported by language compilers

  • Emphasizes writing code after the first chapter

  • Includes substantial examples relevant to intermediate users

What you'll learn

  • Make use of all core language features such as for loops and branching

  • Dynamically manage memory using pointers and indirection

  • Modularize your code through controlling scope and creating functions

  • Move data in and out of your program via keyboard, display monitor, and data files

  • Have the computer write your code for you via preprocesser directives

  • Properly type your data and create structures to manage it efficiently

Who this book is for

Beginning C, 5th Edition is aimed at programmers aspiring to work with C and C-like languages on platforms ranging from mobile devices such as phones and tablets to desktop environments to server hardware. The book is also helpful to programmers working in the field of embedded software, such as that used to control microwaves, toasters, and other home appliances. Any programmer seeking mastery of possibly the most fundational language in existence will find in Beginning C an excellent, sound, standards-based introduction that will serve them well in their career.
