What are exceptions in C++17?

Can you explain what exceptions are in C++17?

Sure! Exceptions in C++ are a way to handle errors or unexpected events in a program. They allow you to separate error handling code from regular code.

How do I throw an exception in C++?

You can throw an exception using the throw keyword followed by an instance of an exception class. For example: throw std::runtime_error("Error occurred");.

What is the difference between checked and unchecked exceptions?

In C++, all exceptions are unchecked, meaning the compiler does not require you to handle them. This is different from languages like Java, which have both checked and unchecked exceptions.

Can you show me an example of a try-catch block?

Certainly! Here's a simple example:

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