+# reversestrcap
+## Instructions
+
+Write a program that takes one or more strings and, for each argument, puts 
+the last character of each word (if it's a letter) in uppercase and the rest
+in lowercase, then displays the result followed by a \n.
+
+A word is a section of string delimited by spaces/tabs or the start/end of the
+string. If a word has a single letter, it must be capitalized.
+
+If there are no parameters, display \n.
+
