I normally do assignments on my own but here's the thing. I'm in a JAVA class and wrote this program in JAVA. Then all of the sudden today my professor goes "oh by the way I actually want this in C". I guess a prereq here for Java students was to take C??? I transferred from another school and haven't taken C so I have no idea where to begin.

Here is the full assignment:
Write a program that takes user input describing a playing card in shorthand notation.

The program can only accept capital letters and can only accept 3 characters max, anything else should print unknown. (For example you can't put in like "00002"
Example:
Enter the card notation: QS
Queen of Spades
Enter the card notation: 10H
Ten of Hearts
