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

C++ exceptions


As the name suggests, exceptions are for exceptional conditions. They are not normal conditions. They are not conditions that you want to occur but they are conditions that may happen. Any exceptional condition will often mean that your data will be in an inconsistent state, so using exceptions means that you need to think in transactional terms, that is, an operation either succeeds, or the state of an object should remain the same as it was before the operation was attempted. When an exception occurs in a code block, everything that happened in the code block will be invalid. If the code block is part of a wider code block (say, a function that is a series of function calls by another function) then the work in that other code block will be invalid. This means that the exception may propagate out to other code blocks further up the call stack, invalidating the objects that depend on the operation being successful. At some point, the exceptional condition will be recoverable...
