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.

Beyond ASCII – UTF-8 and Unicode

The greatest advantage of 7-bit ASCII is that each character in the character set for English can be represented in a single byte. This makes storing text efficient and compact. The greatest disadvantage of 7-bit ASCII is that it represents a character set that is only suitable for English. ASCII can't properly represent other Romance languages based on the Roman alphabet, such as French, Spanish, German, the Scandinavian languages, or the Eastern European languages. For those, we must consider a more comprehensive character-encoding method—Unicode.

If we catalog all of the characters and ideograms for all of the languages on Earth—past and present—we find that 1,112,064 code points are needed to represent all of them with unique values. The term code point is used here instead of character because not all of the positions in this enormous code set are characters; some are ideograms. To represent a code...
