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.

Composition

As the term "composition" implies, when an object contains or possesses another object – in other words, it is composed of another object – we say that there is a composition relationship between them.

As an example, a car has an engine; a car is an object that contains an engine object. Therefore, the car and engine objects have a composition relationship. There is an important condition that a composition relationship must have: the lifetime of the contained object is bound to the lifetime of the container object.

As long as the container object exists, the contained object must exist. But when the container object is about to get destroyed, the contained object must have been destructed first. This condition implies that the contained object is often internal and private to the container.

Some parts of the contained object may be still accessible through the public interface (or behavior functions) of the container class, but the...
