Overview of this book

There’s a lot more to C than knowing the language syntax. The industry looks for developers with a rigorous, scientific understanding of the principles and practices. Extreme C will teach you to use C’s advanced low-level power to write effective, efficient systems. This intensive, practical guide will help you become an expert C programmer. Building on your existing C knowledge, you will master preprocessor directives, macros, conditional compilation, pointers, and much more. You will gain new insight into algorithm design, functions, and structures. You will discover how C helps you squeeze maximum performance out of critical, resource-constrained applications. C still plays a critical role in 21st-century programming, remaining the core language for precision engineering, aviations, space research, and more. This book shows how C works with Unix, how to implement OO principles in C, and fully covers multi-processing. In Extreme C, Amini encourages you to think, question, apply, and experiment for yourself. The book is essential for anybody who wants to take their C to the next level.

Software testing

Software testing is a big and important subject in computer programming, and it has its own specific terminology and many concepts. In this section, we are going to give you a very basic introduction to software testing. Our purpose is to define some terms that we are going to use in the first half of this chapter. Therefore, you should be aware that this is not a thorough chapter about testing and further study is strongly encouraged.

When it comes to testing software, the first question that comes to mind is, what are we testing, and what is this testing about? In general, we test an aspect of a software system. This aspect can be functional or non-functional. In other words, the aspect may be related to a certain functionality of the system, or it can be related to a certain variable of a system when performing a functionality. Next, we give some examples.

Functional testing is about testing a defined functionality requested as part of the functional...
