Arduino 7 segment Number counting with Anode and Cathode

My project is to not let the fake code spread throughout the internet but anyways To do this you will need to have a 7 segment display and a schematics about the 7 segment display hope it's anode or Cathode and the GND or the VCC placed with a 1k resistor and others follow the schematics the INT const <Letter for a display segment> <and the pin that it's connected to>
