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

Understanding uniform initialization


Brace-initialization is a uniform method for initializing data in C++11. For this reason, it is also called uniform initialization. It is arguably one of the most important features from C++11 that developers should understand and use. It removes previous distinctions between initializing fundamental types, aggregate and non-aggregate types, and arrays and standard containers.

Getting ready

For continuing with this recipe, you need to be familiar with direct initialization that initializes an object from an explicit set of constructor arguments and copy initialization that initializes an object from another object. The following is a simple example of both types of initialization, but for further details, you should see additional resources:

    std::string s1("test");   // direct initialization 
    std::string s2 = "test";  // copy initialization

How to do it...

To uniformly initialize objects regardless of their type, use the brace-initialization form ...
