What are the best practices for exception handling in C++?

Some best practices include using exceptions for error handling, avoiding exceptions in destructors, and ensuring that exceptions are caught by reference.

Why should I avoid using exceptions in destructors?

Using exceptions in destructors can lead to program termination if an exception is thrown during stack unwinding. It's safer to handle errors without throwing.

Can you explain the difference between checked and unchecked exceptions?

In C++, all exceptions are unchecked, meaning they are not required to be declared or caught. This differs from languages like Java, which have both types.

What should I do if I can't handle an exception?

If you can't handle an exception, you should let it propagate up the call stack. Ensure that your program can gracefully terminate or recover.

Are there any specific libraries for better exception handling in C++?

Yes, libraries like Boost provide enhanced exception handling features, including better error reporting and handling mechanisms.
