How can I implement custom exception handling in C++?

How can I implement custom exception handling in C++?

You can implement custom exception handling in C++ by creating your own exception classes that inherit from std::exception.

Can you show me an example of a custom exception class?

Sure! Here's a simple example:

class MyException : public std::exception {
public:
    const char* what() const noexcept override {
        return "This is a custom exception!";
    }
};

How do I throw and catch this custom exception?

You can throw it using the throw keyword and catch it in a try-catch block like this:

try {
    throw MyException();
} catch (const MyException& e) {
    std::cout << e.what() << std::endl;
}

What are some best practices for exception handling in C++?

Some best practices include using specific exception types, avoiding exceptions for control flow, and ensuring resource management with RAII.
