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.

Characters – the building blocks of strings

In C, each array element in a string is a character from a character set. In fact, the C character set, also called American Standard Code for Information Interchange (ASCII), is made up of printable characters—those that appear on the screen—and control characters.

Control characters allow digital devices to communicate, control the flow of data between devices, and control the flow data layout and spacing. The following control characters alter how characters are displayed, providing simple character-positioning functions:

  • Horizontal tab (moves the position forward by a number of spaces on the same line)
  • Vertical tab (moves the position to the next line but keeps the current horizontal position)
  • Carriage return (returns the position to the first column)
  • Line feed (advances to the next line)
  • Form feed (advances to the next page)
  • Backspace...
