4) Run the watchdog test programsystem
a. The second parameter 10 represents the counting time of the watchdog. If
there is no dog feeding within this time, the will restart
b. We can feed the dog by pressing any key on the keyboard (except ESC).
After feeding the dog, the program will print a line of keep alive to indicate
that the dog is successfully fed
