How do I handle advanced errors in C++?

In C++, advanced error handling can be achieved using exceptions. You can define custom exception classes and use try-catch blocks.

Can you show me an example of a custom exception?

Sure! Here's a simple example:

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

void riskyFunction() {
    throw MyException();
}

How do I catch this custom exception?

You can catch it like this:

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

What if I want to catch multiple exceptions?

You can catch multiple exceptions by chaining catch blocks:

try {
    // code that may throw
} catch (const MyException& e) {
    // handle MyException
} catch (const std::exception& e) {
    // handle other std exceptions
}
