What are exceptions in C++ and how does the standard library handle them?

Exceptions in C++ are a way to handle errors or unexpected events. The standard library provides mechanisms like try, catch, and throw to manage these exceptions.

Can you give me an example of how to use try and catch?

Sure! Here's a simple example:

try {
    // Code that may throw an exception
    throw std::runtime_error("An error occurred");
} catch (const std::runtime_error& e) {
    std::cout << e.what() << std::endl;
}

What types of exceptions are defined in the standard library?

The standard library defines several exception types, including std::exception, std::runtime_error, std::logic_error, and more, each serving different purposes.

How can I create my own exception class?

You can create your own exception class by inheriting from std::exception and overriding the what() method to provide a custom error message.
