Planning on using a 3-digit seven segment display

Hello!

I am continuing my learning on all the various things that can be done on Arduino. I want to design a system where when you push a button the 3 digit seven segment display goes up by 1. This may be very simple for you guys and honestly I think this code probably already exists somewhere on the internet.

I don't know how to do this, so I was wondering if any of you knew where I could find the code or help me make one I would really appreciate it
