Card trick Java
<p>I have been working on this program for over 30 hours and I am almost as lost now as when i first started. I've finally been able to print out 7 rows of 3 cards but i still have a few issues with my program. </p>

<ol>
<li><p>I need to have the cards line up on the word "of"</p></li>
<li><p>when i call my PrintDeck() function it is supposed to print out all the cards in the deck but it does not.</p></li>
<li><p>I cannot for the life of me figure out how to pick up the columns of cards in order to do the trick, If teh user chooses column 1 i'm supposed to pick it up second and then deal them out again in 7 rows of 3 columns. Then ask them to pick their card 2 more time and do the same thing.</p></li>
</ol>

<p>Any help you could offer would be greatly appreciated. I know some of the code is not very pretty but it has to be that way for the assignment in order for me to get credit :/ Thank you so much for all your help.</p>

<p>instructions: here is a doc if the link works ----> <a href="http://word.office.live.com/wv/WordView.aspx?FBsrc=https://www.facebook.com/attachments/doc_preview.php?mid=id.376414855713455&amp;id=05ba139ea8f82045adb02272e74d6bf2&amp;metadata&amp;access_token=1850923532%3aAQBxvI0QdjuXTt48&amp;title=Cardtrick%20Instructions%20-%20Java" rel="nofollow">instructions doc</a>
Program Requirements:</p>

<p>Your program must generate its own random deck of cards using the following technique:</p>

<ul>
<li><p>generate a random integer for each card</p></li>
<li><p>display a string value for each card ("Ace of Diamonds")</p></li>
<li><p>use the rand() function to generate integer card values</p></li>
<li><p>use the srand(time(0)) command (only once at the beginning of the program) to generate a truly random deck once the program has been tested and runs properly.</p></li>
</ul>

<p>Each value must be converted to the format  of  as done in the example above. Whenever your program displays the cards they must line up as they do above, on the word "of".<br>
Your program must deal the cards out by row and pick them up by column (3 times to make it work properly).<br>
Your program must ask the player is he/she wants to printout the entire deck before playing. Each card must be printed out formatted as above.<br>
Your program must ask the player if he/she wants to play again, and continue playing as many times as the player wants.<br>
The program must ask the player for his/her name and refer to the player by name throughout the playing of the game.<br>
Your program code must be logically organized using functions. You also must use the starter file provided. You will GET A ZERO (0) if you do not use the starter file!  </p>
