hangman again

[Hyena]

there is a minor problem with hangman; whenever a word is randomly chosen, if it is less then six letters, the program attaches junk to the end until it equals six characters (junk is random characters ' X . )what shall i do?

Take a look at this: (note: it gets the words from words.dat located in same directory)
