function def = dictionary(file,word) % Given the name of a .txt file and one word you are looking for, return % the definition of the word. All dictionary entries in the text file % will be on one line, and the word and its definition will be separated % by a dash. See dictionary.txt for further details. Your definition % should not have leading dashes or spaces before it.
