I'm sorry, but what exactly is your question?

Also, when you're posting code, you can use code-tags (put [code] in front of your code, and [/code] behind it, and it will be nicely formatted). Other guidelines like this and rules can be found in the faq.

You have still not asked a question!

If you are having a prblem with the post code then you need to either post any compiler and linker errors you are getting or post a description of the runtime errors including, expected behaviour, actual behaviour, input data, output.

Additionally you need to have the courtesy to actually ask for the help you require.

Hey all, I want to create a computerised version of this game, though I'm not really sure how to go about it. For those who don't know how the game works, here's my attempt at a brief description: It is very similar to the card game Uno, though played with a standard deck of cards. An initial card is played off the top of the deck, and then each player has to play a card of the same suit, or the same face value in another suit....

Hi there I need to make a Craps game for my class. Here are the parameters for it. In the game of craps, a pass line bet proceeds as follows. Two six-sided dice are rolled; the first roll of the dice in a craps round is called the “come out roll.” A come out roll of 7 or 11 automatically wins, and a come out roll of 2, 3, or 12 automatically loses. If 4, 5, 6, 8, 9, or 10 is rolled on the come out roll, that number becomes “the point.” The...
