Hello everyone, I'm working on a card trick program that essentially has the user pick a card and the program will figure out which card it is. However, When I get the the displayed cards, I get some results that have no value and some that are not alligned properly. I also am having an issue with getting a loop created in order to make the program loop itself until the user is done. Here is my code: `
/* File: Cardtrick.cpp
* Programmer: Dakotah Goetz
* Date: 7-5-17
* Course: COP 2931
*
* Purpose:
* Write a program that performs a cardtrick. The program will create a
* random deck of cards, deal them out, pick them up, and determine the
* secret card.
*

Hello, I am a really tricky computer program and
I can even perform a card trick. Here's how.
To begin the card trick type in your name: dak
Thank you, Dak.
Ok Dak, first things first. Do you want to see what
the deck of cards looks like (1 = y/0 = n)? 1
Dak, pick a card and remember it...
Column 0 Column 1 Column 2
=======================================================
8 of Diamonds 8 of Spades of Diamonds
6 of Spades 8 of Hearts Queen of Spades
Queen of Diamonds 10 of Diamonds 8 of Clubs
6 of Diamonds 5 of Hearts 2 of Clubs
10 of Hearts 9 of Diamonds 2 of Hearts
6 of Clubs 4 of Spades 10 of Clubs
of Hearts of Diamonds 9 of Hearts
Which column is your card in (0, 1, or 2)?: 0
Column 0 Column 1 Column 2
=======================================================

Your secret card is: 8 of Clubs
Dak, would you like to play again (y/n)? y
Thank you for playing the card trick!
Press any key to continue . . .I am not asking anyone to do the homework for me, but any pointers and help will be greatly appreciated!
