HELP PLEASE!!!

[sbgreen6592]

Ok, so I need to write the following functions,
a) int first_digit (int n), returning the first digit of the argument
b) int last_digit (int n), returning the last digit of the argument
c) int digits (int n), returning the number of digits of the argument

I am in an intro computer science class and am extremely confused as to what to do. If you could please help, I would greatly appreciate it!!!!

I know, but I used something completely different. I have no idea even where to begin.

What is completely different? Here and there the same function that returns the number of digits.
