When should I use std::exception in C++?

When should I use std::exception in C++?

You should use std::exception when you want to handle errors in a standardized way. It provides a base class for all exceptions.

Can you give me an example of how to implement it?

Sure! You can create a custom exception by inheriting from std::exception and overriding the what() method to provide an error message.

What are the benefits of using exceptions over error codes?

Using exceptions allows for cleaner code, better separation of error handling, and automatic stack unwinding, which can simplify resource management.

Are there any performance concerns with using exceptions?

Yes, exceptions can introduce overhead, especially if they are thrown frequently. It's best to use them for exceptional cases rather than regular control flow.
