C Language: Write a diagnostic code for the following code. And please tell me what it will check for. This code does the following: its using 2 7 Segment LEDs

Hit Switch

Count Up

Hit Switch

Display Time

Hit Switch

Count Down from 99

Hit Switch

Display time

Hit Switch

Turn off display

The diagonistic code should check: All segement of the LEDs and or buttons to make sure they work fine.
