What is the performance impact of exceptions in C++?

What is the performance impact of exceptions in C++?

Exceptions in C++ can introduce overhead due to stack unwinding and the need for additional memory management.

How does stack unwinding affect performance?

Stack unwinding can slow down performance because it involves cleaning up the stack frames, which can be costly in terms of time.

Are there ways to minimize this overhead?

Yes, you can minimize overhead by using exceptions sparingly, optimizing your code paths, and considering alternative error handling methods.

What are some alternatives to using exceptions?

Alternatives include using error codes, assertions, or even custom error handling classes that avoid the overhead of exceptions.
