Assignment 08

Details:

• Remember that you can work with a partner, but you have to have the same instructor. No exceptions! None!!

• Each of the bingo card files is formatted as 5 single (lowercase) words on 5 lines (that's 25 total words), each word separated by a comma, no spaces; each word can be at most 15 chars long; no comma after each fifth word.

• Each of the sayings files is formatted with the first line containing an integer indicating how many sayings there are in the file, and the remaining lines each have a saying of at most 256 chars.

• If the "bad" word begins with an uppercase letter in the saying, then the "good" word it is replaced with must also begin with an uppercase letter in the saying.

• Each of the two contestants must check for words in the (sanitized) sayings in their bingo cards; and, for a match, case doesn't matter.

• The telephone conversation (and hence the game) ends when either one of the players gets BINGO or 20 rounds (NOT individual utterances) of Beatrice and BoJack saying something have been completed.

• At the end of the conversation (and hence the game), Beatrice and BoJack should say 'goodbye' to each other, and you should output the results of the Bingo game; the Bingo game can end in 1 of 3 possible ways: (1) no one won (i.e., it was over because 20 rounds of the telephone conversation finished), or (2) one of the contestants got BINGO (see below), or (3) both of the contestants got BINGO in the same round (so it was a tie).

• How someone wins at BINGO:

  • You match all words in a row, or

  • You match all words in a column, or

  • You match all words in a major diagonal.

    • • Note: Any position that has the word "*" in it is an automatic match

Output: In addition to displaying on the screen who the winner is, you must write the contents of that person's Bingo card to both the screen and a file. If that is the first contestant, write it to a file named winningBingoCard1.dat. If it is the second contestant, write it to a file named winningBingoCard2.dat. If there was a tie, write both files. If no one won, you don't have to write either of these files. In any case, indication of the outcome needs to go to the screen.

When you output (file and screen) a winning card, write each of the 5 words of a row of the Bingo card to a line separated by at least one space. Put [ ]'s around the words that were involved in the winning Bingo combination for that card so that we can see how the contestant won (i.e., which row, column, or diagonal entries they matched).

Now one last thing...any winner of anything deserves a prize. Wouldn't you agree? So, if there is either a single winner or a tie (two winners), then your code should pick at random a prize (or prizes) from the WinnersPrize.dat file and announce it for the one (or the pair). The format of the prize file is that each prize will be on a single line no more than 100 characters, and there is no indication in the file as to how many prizes are in the file. You can count on there being a newline char at the end of each line. You are not to modify the file.

Now for the data files: There are five (5) files that you need for this assignment. To save you the trouble (aren't we kind?!) of creating them, I've created them in my directory and I'm giving you a method to download them easily into your directory. First, create in your sdrive a directory for your hw8 files. Then change into that directory and type the following commands at the unix prompt:

• wget http://web.mst.edu/~price/1570/bingoCard1.dat

• wget http://web.mst.edu/~price/1570/bingoCard2.dat

• wget http://web.mst.edu/~price/1570/BojackSayings.dat

• wget http://web.mst.edu/~price/1570/BeatriceSayings.dat

• wget http://web.mst.edu/~price/1570/WinnersPrize.dat

You should issue the ls command at the end of this to check to see that you have indeed obtained those files. Open them to make sure the data is there, but don't alter it!

But wait, there's more! You are required to use only null-terminated character arrays (c-strings) for this assignment (not std strings). Furthermore, you are NOT to read in all the contents at one time of any sentence or prize file and store them internally in your program. Of course, you need to read in the bingo card files at once and store them.

When you submit: As you develop your code, seed the rng with time. But when you submit, seed with this magic value: 1522258756. And, use the names "Todd" and "Mr. Peanutbutter" as the players.

Note: Don't underestimate the difficulty of this assignment. Start early!

One final note: We would like to make it clear that no horse-headed animated creatures were harmed in the making of this web page. Perhaps a few were insulted, but they most certainly deserved it. The SPCA (Society for the Prevention of Cruelty to Animations) has give their blessings to this exercise.
