What is the throw keyword in C++?

Can you explain the throw keyword in C++?

Sure! The throw keyword in C++ is used to signal the occurrence of an exception. It allows you to throw an exception object when an error occurs.

How do I use the throw keyword in my code?

You can use it like this: throw exceptionObject; where exceptionObject is an instance of an exception class.

What types of exceptions can I throw?

You can throw any object derived from the std::exception class or any custom exception class you create.

Can you give me an example of a custom exception?

Certainly! Here's a simple example:

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

throw MyException();
