Error codes are return values indicating failure, while exceptions are objects that signal an error and can be caught.

Sure! In C++, a function might return -1 to indicate an error, and the caller checks this value to handle the error.

How do exceptions work in C++?

Exceptions in C++ are thrown using the 'throw' keyword and can be caught with 'try' and 'catch' blocks.
