What is the difference between exceptions and assertions in C++?

What is the difference between exceptions and assertions in C++?

In C++, exceptions are used for error handling at runtime, while assertions are used to check assumptions during development.

Can you give me an example of when to use an exception?

Sure! Use exceptions when you encounter an unexpected error, like trying to open a file that doesn't exist.

And what about assertions? When should I use them?

Assertions are best used to catch programming errors during development, like checking if a pointer is not null before dereferencing it.

Are there performance implications for using assertions?

Yes, assertions can be disabled in release builds, which can improve performance, but they should not replace proper error handling.

So, should I rely on assertions for error handling?

No, assertions should not replace exceptions; they are meant for debugging, while exceptions handle runtime errors.
