What are the different exception types in C++20?

C++20 introduces several new exception types, including std::bad_alloc, std::bad_cast, and std::bad_typeid. These are used for handling specific error conditions.

Can you explain std::bad_alloc in more detail?

Sure! std::bad_alloc is thrown when memory allocation fails. It's part of the standard library and helps in managing memory-related errors.

What about std::exception? How does it relate to other exception types?

std::exception is the base class for all standard exceptions in C++. Other exception types, like std::bad_alloc, inherit from it, allowing for polymorphic behavior.

Are there any new features in C++20 related to exception handling?

Yes, C++20 introduced the concept of 'noexcept' specifications, which allow you to indicate whether a function can throw exceptions, improving performance and safety.
