I am trying to write a loop that will display the 20 most recent calculations inputed and display them. When it loops the 21st time, I need it to kick the first value out and move everything else up. I was thinking of using a for loop to do this but I am unsure of how to start it.
It sounds like you want to use a circular buffer, which overwrites from the beginning when it gets full. To accomplish this, just index the array modulo the array size and make sure you don't overwrite anything you still need.

Why didn't you keep this with your original thread in which I suggested a circular linked list?
