What are the differences between function pointers and arrays of functions?

Function pointers are variables that store the address of a function, allowing dynamic function calls. Arrays of functions, on the other hand, are collections of function pointers, enabling you to call multiple functions in a structured way.

Can you give me an example of when to use each?

Sure! Use function pointers for callbacks or when you need to pass a function as an argument. Use an array of functions when you want to manage a set of related functions, like handling different events.

What are the performance implications of using one over the other?

Function pointers can introduce slight overhead due to indirection, but they are generally efficient. Arrays of functions can be more organized and may improve readability, but they also require managing the array size.

Are there any limitations to using function pointers?

Yes, function pointers can lead to complexity in code management and debugging. Additionally, they can only point to functions with matching signatures.
