What is the difference between error codes and exceptions in C++?

What is the difference between error codes and exceptions in C++?

In C++, error codes are returned by functions to indicate success or failure, while exceptions are used for handling errors through a separate control flow.

Can you give me an example of using error codes?

Sure! A function might return an integer error code, like -1 for failure, and you check this code after calling the function.

How do exceptions work in C++?

Exceptions in C++ are thrown using the 'throw' keyword and can be caught using 'try' and 'catch' blocks, allowing for cleaner error handling.

Which method is preferred in modern C++?

Modern C++ tends to favor exceptions for error handling as they provide a clearer and more manageable way to deal with errors.
