The WordGuess game :
When the user plays WordGuess, the computer first selects a secret word at random from a list built into the program. The program then prints out a row of dashes—one for each letter in the secret word and asks the user to guess a letter. If the user guesses a letter that is in the word, the word is redisplayed with all instances of that letter shown in the correct positions, along with any letters correctly guessed on previous turns. If the letter does not appear in the word, the user is charged with an incorrect guess.
