What are some design patterns for exception safety in programming?

Some common design patterns for exception safety include RAII (Resource Acquisition Is Initialization), the use of smart pointers, and the copy-and-swap idiom.

Can you explain RAII in more detail?

RAII is a programming idiom where resources are tied to the lifetime of objects. When an object is created, it acquires resources, and when it goes out of scope, it releases them, ensuring no resource leaks even in the presence of exceptions.

What is the copy-and-swap idiom?

The copy-and-swap idiom is a technique for implementing assignment operators. It involves creating a copy of the right-hand side object and then swapping it with the current object, ensuring strong exception safety.

Are there any other patterns I should know about?

Yes, other patterns include using try-catch blocks effectively, implementing error codes, and designing functions to be exception-safe by default.
