Write the code that will show A when energy is given the system and then none of buttons are pressed and will show B when no1 button is pressed 10 times just after A and will show C when no2 button is pressed 10 times just after A. (The code should work when a button is pressed not just 10 times but also for example 5 or 6 times. )

(OSC -> 8MHz)

CCP1 should be used. 8 bit should be preffered.
