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 standard output stream

The standard output stream is a pointer to a complex FILE structure named stdout. This stream sends all characters to the console screen formatted by the printf() function. We can think of this stream as a never-ending flow of characters from our program to the screen. It may not look like that onscreen because of the control characters, which alter how characters appear. These include carriage return (CR), new line (NL), form feed (FF), horizontal tab (HT), and vertical tab (VT). Other control characters change how the screen appears when we delete or rub out characters. These include backspace (BS) and delete (DEL). Nevertheless, these characters appear in the stream flow to the console program; the console program either simply prints them or interprets and changes the position of where the next character will be shown on the screen.

One complication to the flow of characters in the stream is that they aretypically buffered....
