C++11: std::exception vs Error Codes

What is the difference between std::exception and error codes in C++?

In C++, std::exception is a class for handling exceptions, while error codes are integers or enums indicating errors.

When should I use exceptions instead of error codes?

Use exceptions for critical errors that disrupt normal flow, and error codes for recoverable or minor issues.

Can you give an example of using std::exception?

Sure! You can throw a std::runtime_error when a function fails, and catch it to handle the error gracefully.

Are there performance implications of using exceptions?

Yes, exceptions can be more expensive in terms of performance, especially if thrown frequently. Use them judiciously.
