How do exceptions affect performance in C++?

Exceptions in C++ can introduce overhead due to stack unwinding and the need for additional code to handle them.

Is it better to use error codes instead of exceptions for performance?

Using error codes can be more performant in critical sections, but it sacrifices readability and maintainability.

What are some best practices for using exceptions in C++?

Best practices include using exceptions for exceptional cases only, avoiding throwing exceptions in destructors, and ensuring exception safety.

Can you give an example of exception handling in C++?

Sure! Here's a simple example:

try {
    // code that may throw
} catch (const std::exception& e) {
    // handle exception
}
