Hands-On Design Patterns with C++

A comprehensive guide with extensive coverage on concepts such as OOP, functional programming, generic programming, and STL along with the latest features of C++

Key Features

• Delve into the core patterns and components of C++ in order to master application design
• Learn tricks, techniques, and best practices to solve common design and architectural challenges
• Understand the limitation imposed by C++ and how to solve them using design patterns

Book Description

C++ is a general-purpose programming language designed with the goals of efficiency, performance, and flexibility in mind. Design patterns are commonly accepted solutions to well-recognized design problems. In essence, they are a library of reusable components, only for software architecture, and not for a concrete implementation.

The focus of this book is on the design patterns that naturally lend themselves to the needs of a C++ programmer, and on the patterns that uniquely benefit from the features of C++, in particular, the generic programming. Armed with the knowledge of these patterns, you will spend less time searching for a solution to a common problem and be familiar with the solutions developed from experience, as well as their advantages and drawbacks. The other use of design patterns is as a concise and an efficient way to communicate. A pattern is a familiar and instantly recognizable solution to specific problem; through its use, sometimes with a single line of code, we can convey a considerable amount of information. The code conveys: “This is the problem we are facing, these are additional considerations that are most important in our case; hence, the following well-known solution was chosen.”

By the end of this book, you will have gained a comprehensive understanding of design patterns to create robust, reusable, and maintainable code.
