Modern C++: Efficient and Scalable Application Development

By: Richard Grimes, Marius Bancila

Overview of this book

C++ is one of the most widely used programming languages. It is fast, flexible, and used to solve many programming problems. This Learning Path gives you an in-depth and hands-on experience of working with C++, using the latest recipes and understanding most recent developments. You will explore C++ programming constructs by learning about language structures, functions, and classes, which will help you identify the execution flow through code. You will also understand the importance of the C++ standard library as well as memory allocation for writing better and faster programs. Modern C++: Efficient and Scalable Application Development deals with the challenges faced with advanced C++ programming. You will work through advanced topics such as multithreading, networking, concurrency, lambda expressions, and many more recipes. By the end of this Learning Path, you will have all the skills to become a master C++ programmer. This Learning Path includes content from the following Packt products: • Beginning C++ Programming by Richard Grimes • Modern C++ Programming Cookbook by Marius Bancila • The Modern C++ Challenge by Marius Bancila

Using Pointers in Practice


A common requirement is to have a collection that can be an arbitrary size and can grow and shrink at runtime. The C++ Standard Library provides various classes to allow you to do this, as will be described in Chapter 5, Using the Standard Library Containers. The following example illustrates some of the principles of how these standard collections are implemented. In general, you should use the C++ Standard Library classes rather than implementing your own. Further, the Standard Library classes encapsulate code together in a class and since we have not covered classes yet, the following code will use functions that potentially can be called incorrectly. So, you should regard this example as just that, example code. A linked list is a common data structure. These are typically used for queues where the order of items is important. For example, a first-in-first-out queue where tasks are performed in the order that they are inserted in the queue. In this example...
