C Programming

I am quite new to c programming but i was wondering if any one can help me.

i have a unsigned int yearEnrolled = 2001

and i need to be able to detect or assign the last digit of yearEnrolled.  So then i can use a switch statement to produce a ID - eg. if last digit is 0 = A, 1 = B etc.  
Does anyone know how i can do this by only getting the last digit.

yearEnrolled mod 10

This will return the remainder of the integer yearEnrolled divided by 10.  Which is always the 1's digit

unsigned int yearEnrolled = 2001;
unsigned int lastdigit = yearEnrolled % 10;
char ID='A'+lastdigit;
