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

Memory and the C++ Standard Library

The C++ Standard Library provides various classes to allow you to manipulate collections of objects. These classes, called the Standard Template Library (STL), provide a standard way to insert items into collection objects and ways to access the items and iterate through entire collections (called iterators). The STL defines collection classes that are implemented as queues, stacks, or as vectors with random access. These classes will be covered in depth Chapter 5, Using the Standard Library Containers, so in this section we will limit the discussion to just two classes that behave like C++ built in arrays.

Standard Library arrays

The C+ Standard Library provides two containers that give random access via an indexer to the data. These two containers also allow you to access the underlying memory and since they guarantee to store the items sequentially and contiguous in memory, they can be used when you are required to provide a pointer to a buffer.
