How do exceptions affect performance in C++?

How do exceptions affect performance in C++?

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

Are there ways to minimize the performance impact of exceptions?

Yes, you can minimize the impact by using exceptions sparingly, avoiding exceptions in performance-critical code, and using error codes instead.

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

Best practices include using exceptions for exceptional cases only, ensuring that your code is exception-safe, and documenting the exceptions your functions may throw.

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
}
