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

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

Exceptions in C++ can significantly impact performance, especially if they are thrown frequently. They can lead to increased overhead due to stack unwinding and the need for additional memory allocation.

Are there specific scenarios where exceptions are more costly?

Yes, exceptions can be more costly in scenarios where they are used in performance-critical code, such as tight loops or real-time systems. It's often better to use error codes in such cases.

How can I minimize the performance impact of exceptions?

To minimize the impact, you can use exception handling sparingly, avoid throwing exceptions in performance-critical paths, and consider using alternative error handling strategies.

What are the alternatives to using exceptions?

Alternatives include using return codes, optional types, or result types that encapsulate success and error states without throwing exceptions.
