You have to think ahead. You have 96 numbers now, but after 96 you have to change the data type to a larger storage to be able to store larger numbers. So when you pre-calc say 10,000 numbers what happens to your array then? What if the program is run on an embedded system for some reason that has memory limits? Like say someone finds a reason to use Fibonacci numbers on an embedded system to monitor machines and control machines and other stuff?

You don't know a reason to use Fibonacci numbers, but that doesn't mean someone else might find a way to use them.

You haven't worked with embedded systems, have you? 96 numbers is 384 bytes. That's a lot of space for some applications.
