Software design patterns are a valuable tool in any software developer's skill set. However, most design patterns are described in the context of an object-oriented programming language such as C++ or Java. The C language is sadly absent in the pattern literature. This course is here to change that by demonstrating that it is possible to use patterns in C programs and how it adds benefits to C programmers. You will learn why design patterns are more of a communication tool than technical solutions, and how patterns let you build and share a common vocabulary that simplifies communication.

The course presents a number of patterns and explains how to implement them in C. Each pattern is introduced via the problem it solves and the domains where the pattern can be used. We also discuss the underlying design principles as well as the trade-offs when applying the pattern. Finally, the course covers a set of coding idioms that will guide you when applying design patterns in C.

Software Design Patterns in C

As a language evolves, certain efficient patterns arise. These patterns get used with such a high frequency
and naturalness that they almost grow together with the language and generate an idiomatic usage for
the language practitioner. The resulting idiomatic expressions often seem peculiar to a newcomer
of the language. This holds equally true for both natural and computer languages; even a programmer not
using the idioms has to know them to be efficient at reading other peoples’ code.
