When should I use exceptions in C++?

When should I use exceptions in C++?

You should use exceptions in C++ for error handling when an error occurs that cannot be handled locally. This allows you to separate error handling from regular code flow.

Can you give me an example of when to use exceptions?

Sure! For instance, if you're reading from a file and the file doesn't exist, throwing an exception allows you to handle that error gracefully instead of crashing the program.

Are there any downsides to using exceptions?

Yes, exceptions can introduce overhead and complexity. They can also make code harder to read if overused, so it's important to use them judiciously.

What are some best practices for using exceptions?

Best practices include using exceptions for exceptional cases only, ensuring that your code is exception-safe, and documenting the exceptions your functions can throw.
