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 and Aggregation

In the previous chapter, we talked about encapsulation and information hiding. In this chapter, we continue with object orientation in C and we'll discuss the various relationships that can exist between two classes. Eventually, this will allow us to expand our object model and express the relations between objects as part of the upcoming chapters.

As part of this chapter, we discuss:

  • Types of relations that can exist between two objects and their corresponding classes: We will talk about to-have and to-be relationships, but our focus will be on to-have relations in this chapter.
  • Composition as our first to-have relation: An example will be given to demonstrate a real composition relationship between two classes. Using the given example, we explore the memory structure which we usually have in case of composition.
  • Aggregation as the second to-have relation: It is similar to composition since both of them address a to-have relationship...
