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

Summary


Functions allow you to segment your code into logical routines, which makes your code more readable, and gives the flexibility of being able to reuse code. C++ provides a wealth of options to define functions, including variable argument lists, templates, function pointers, and lambda expressions. However, there is one main issue with global functions: the data is separate from the function. This means that the function has to access the data via global data items, or data has to be passed to a function via a parameter every time the function is called. In both cases, the data exists outside the function and could be used by other functions unrelated to the data. The next chapter will give a solution to this: classes. A class allows you to encapsulate data in a custom type, and you can define functions on that type so that only these functions will be able to access the data.
