C++ Error Handling vs Return Codes

What are the main differences between error handling and return codes in C++?

In C++, error handling typically involves using exceptions, while return codes are a way to indicate success or failure through function return values.

Can you explain how exceptions work in C++?

Sure! Exceptions in C++ allow you to handle errors by throwing an exception object when an error occurs, which can then be caught and handled in a separate block of code.

When should I use return codes instead of exceptions?

Return codes are often used in performance-critical applications where exceptions might introduce overhead, or in simpler functions where error handling is straightforward.

Are there any best practices for using exceptions in C++?

Yes, some best practices include using exceptions for exceptional cases only, ensuring proper resource management, and documenting the exceptions your functions can throw.
