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 the string class as a container

C++ strings are based on the basic_string template class. This class is a container, so it uses iterator access and methods to obtain information, and has template parameters that contain information about the character type it holds. There are different typedef for specific character types:

    typedef basic_string<char,
       char_traits<char>, allocator<char> > string; 
    typedef basic_string<wchar_t,
       char_traits<wchar_t>, allocator<wchar_t> > wstring; 
    typedef basic_string<char16_t,
       char_traits<char16_t>, allocator<char16_t> > u16string; 
    typedef basic_string<char32_t,
       char_traits<char32_t>, allocator<char32_t> > u32string;

The string class is based on char, wstring is based on wchar_t wide characters, and the 16string and u32string classes are based upon 16-bit and 32-bit characters, respectively. For the rest of the chapter, we will concentrate...
