And running the program and setting the word from within the program would look like:

You need to know the following concepts in order to write this program:

Everything from the previous programs, single and 2 dimensional arrays, binary search, reading from a file, implementing a timer to test elapsed time.

Hints:

• 1. (0 points) To start read in all 7660 words in this dictionary.  Note that it contains only words that are between 3 and 6 characters in length.  As you go count how many 6-letter words there are.  See this sample program illustrating how to read from a file.

  2. (5 points) Select a random 6-letter word in the dictionary.

  3. (15 points) Find all possible words which can be created from those 6 letters, which are found in the dictionary.  The listed words must be unique.

  4. (8 points) Create the playing surface, leaving space for each possible word.  You will need to store these in an array.

  5. (10 points) Allow guessing words, comparing to found words and updating displayed as play progresses.  If a word cannot be formed with the given letters, give an error message and allow retrying the move.

  6. (2 points) Implement a timer to limit program to 60 seconds.  Check for elapsed time after each move. See this program for an example.

  7. (15 points) Implement the twist, cheat and set options.
