What are advanced techniques for exception handling in C++?

Advanced techniques for exception handling in C++ include using custom exception classes, RAII (Resource Acquisition Is Initialization), and the noexcept specifier.

Can you explain how RAII works in exception handling?

RAII ensures that resources are properly released when an exception occurs. By tying resource management to object lifetime, C++ automatically cleans up resources when an object goes out of scope.

What are custom exception classes and how do I create one?

Custom exception classes allow you to define specific error types. You create one by inheriting from std::exception and overriding the what() method to provide a custom error message.

How does the noexcept specifier improve exception handling?

The noexcept specifier indicates that a function does not throw exceptions, allowing for optimizations and better performance, as the compiler can make certain assumptions.
