C++ exceptions provide a powerful foundation for exception handling design. They are flexible and may be used in multiple different ways. You can throw exceptions of any type, including pointers and integers. You can catch exceptions by value or by reference.

In this recipe, we will analyze potential pitfalls and learn how to use constant references in catch blocks for efficient and safe error handling.
