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.

Exploring Formatted Output

In previous chapters, all the input was provided within each program and all the output was sent in rather simple forms to the console (screen). In this chapter, we will expand on more sophisticated output formatting. However, what if we need a precise layout of numbers and text? We saw in Chapter 15, Working with Strings, how to precisely generate a table of ASCII characters. With full knowledge of the possibilities of output formatting, very precise tables of numbers can be created. Furthermore, other kinds of precisely formatted documents can be generated, such as invoices, product price lists, and many others.

The C printf() function provides a rich set of formatting options, far beyond what we have used up to this point. We can format numbers—both integers and decimal numbers—characters, and strings in many ways. In this chapter, we will explore, primarily through examples...
