Overview of this book

The foundation for many modern programming languages such as C++, C#, JavaScript, and Go, C is widely used as a system programming language as well as for embedded systems and high-performance computing. With this book, you'll be able to get up to speed with C in no time. The book takes you through basic programming concepts and shows you how to implement them in the C programming language. Throughout the book, you’ll create and run programs that demonstrate essential C concepts, such as program structure with functions, control structures such as loops and conditional statements, and complex data structures. As you make progress, you’ll get to grips with in-code documentation, testing, and validation methods. This new edition expands upon the use of enumerations, arrays, and additional C features, and provides two working programs based on the code used in the book. What's more, this book uses the method of intentional failure, where you'll develop a working program and then purposely break it to see what happens, thereby learning how to recognize possible mistakes when they happen. By the end of this C programming book, you’ll have developed basic programming skills in C that can be easily applied to other programming languages and have gained a solid foundation for you to build on as a programmer.

Chapter 19: 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 15Working 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 and product price lists, for example.

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, the various ways in which...
