How do function pointers affect performance in C++?

How do function pointers affect performance in C++?

Function pointers can introduce some overhead due to indirect calls, but they also enable flexibility in code.

Can you explain the trade-offs between using function pointers and direct function calls?

Direct function calls are faster due to less overhead, while function pointers offer more dynamic behavior.

Are there specific scenarios where function pointers are preferred?

Yes, function pointers are useful in callback mechanisms, event handling, and implementing polymorphism.

How can I measure the performance impact of using function pointers?

You can use profiling tools to compare execution times of code with and without function pointers.
