Overview of this book

C++ is a general-purpose programming language designed for efficiency, performance, and flexibility. 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. This book helps you focus on the design patterns that naturally adapt to your needs, and on the patterns that uniquely benefit from the features of C++. Armed with the knowledge of these patterns, you’ll spend less time searching for solutions to common problems and tackle challenges with the solutions developed from experience. You’ll also explore that design patterns are a concise and efficient way to communicate, as patterns are a familiar and recognizable solution to a specific problem and can convey a considerable amount of information with a single line of code. By the end of this book, you’ll have a deep understanding of how to use design patterns to write maintainable, robust, and reusable software.

A Comprehensive Look at RAII

Resource management is probably the second most frequent thing a program does, after computing. But just because it’s frequently done does not mean it’s visible—some languages hide most, or all, resource management from the user. And just because it is hidden, does not mean it’s not there.

Every program needs to use some memory, and memory is a resource. A program would be of no use if it never interacted with the outside world in some way, at least to print the result, and input and output channels (files, sockets, and so on) are resources.

In this chapter, we will start by answering the following questions:

  • What is considered a resource in a C++ program?
  • What are the key concerns for managing resources in C++?

Then, we will introduce Resource Acquisition is Initialization (RAII) and explain how it helps in efficient resource management in C++ by answering these questions:

  • What is the standard...
