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

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

Exceptions in C++ can introduce overhead, especially if they are frequently thrown and caught. The performance impact varies based on the implementation and usage patterns.

Can you explain how exception handling affects optimization?

Certainly! Compilers often optimize code differently when exceptions are involved, which can lead to less efficient code paths if exceptions are used extensively.

Are there best practices to minimize the performance cost of exceptions?

Yes, some best practices include using exceptions for truly exceptional cases, avoiding exceptions in performance-critical code, and ensuring that exception handling is as lightweight as possible.

What alternatives to exceptions can be used in C++?

Alternatives include error codes, optional types, or using the Result pattern, which can provide more predictable performance without the overhead of exceptions.
