How do error handling mechanisms differ between C and C++?

In C, error handling is typically done using return codes and global variables like errno. In contrast, C++ offers exceptions, which provide a more structured way to handle errors.

Can you explain how exceptions work in C++?

Sure! In C++, exceptions are thrown using the 'throw' keyword and caught using 'try' and 'catch' blocks. This allows you to separate error handling from regular code.

What are the advantages of using exceptions over return codes?

Using exceptions can lead to cleaner code, as it separates error handling from business logic. It also allows for stack unwinding, which can help manage resources more effectively.

Are there any downsides to using exceptions?

Yes, exceptions can introduce overhead and complexity. They may also lead to performance issues if not used judiciously, especially in performance-critical applications.
