Your checklist

For your own tracking. Tests grade your code.

Each argument is printed on its own line, followed by a newline.
A word is a sequence of characters bounded by spaces, tabs, or the start or end of the string.
The first character of each word must be uppercased if it is a letter; all other letters in that word must be lowercased.
Non-alphabetic characters such as digits and punctuation are left unchanged.
If no arguments are supplied (argc is 1), print wrong number of arguments followed by a newline.
