What is the difference between error handling and exception handling in C++?

What is the difference between error handling and exception handling in C++?

In C++, error handling typically involves checking return values and using error codes, while exception handling uses try-catch blocks to manage errors.

Can you give me an example of each?

Sure! For error handling, you might check if a file opened successfully by examining the return value. For exception handling, you would wrap the file operation in a try block and catch any exceptions that occur.

Which method is preferred in modern C++?

Modern C++ generally favors exception handling because it separates error handling code from regular code, making it cleaner and easier to maintain.

Are there any performance implications of using exceptions?

Yes, exceptions can introduce overhead, especially if they are thrown frequently. However, when used judiciously, they can lead to more robust code.
