Question

c++

For this project, you will create a program that will later be used as part of a magic trick. Your program will create a deck of playing cards. The user will be prompted to select a card from the list and that card will be put on the top of the deck.

Minimum Requirements:

Create a playing card node class and a deck of cards linked list class. You cannot use the STL list class for this assignment (5 points).

Include a function to add cards to the deck (5 points). The head node in the list represents the top of the deck. Each node will represent each playing card and should hold two private variables: a string containing the suit and another string with the value of a card. For example, the suit would include Spades, Hearts, Clubs and Diamonds. The values would include King, Queen, Ace, 2, 3, etc.

Include a display function in the deck class that displays the data from each card (5 points).

Include another function in the deck class that asks the user to select a card. Then, it.will find the selected card and move it to the top of the deck. This will move that card node from its original position in the list to the head of the list. (5 points)

The main method should call the add function to add a few cards to the deck for testing. It should then call the display function, then call the function that moves the card. Finally, it should call the display function again to show the deck with the selected card listed first.

Solution:

card.h

#ifndef card_h
#define card_h
#include <iostream>
using std::string;
class card
{
private:
string suit;
string value;
card* next;//pointer to next card
public:
card(string suit, string value);
void setSuit(string suit);
void setValue(string value);
string getSuit();
string getValue();
card* getNext();
void setNext(card* n);
};

#endif /* card_h */

}
card* card::getNext()

}
void deck::moveToTop(string suit, string value)
{

if(curr->getSuit() == suit && curr->getValue() == value)

}
  
if(curr == NULL) //not found
cout << " No card " << value << " of " << suit << endl << endl;

}
  
}
void deck::select()

cout << "Enter suit: ";
cin >> suit;

}
void deck::display()
{

}
cout << endl;
}

main.cpp

#include <iostream>

#include "deck.h"
using namespace std;
int main()
{
deck d;
d.addCard("Diamonds", "Ace");
d.addCard("Clubs", "5");
d.addCard("Hearts", "9");
d.addCard("Spades", "King");
d.addCard("Diamonds", "Jack");
  
cout << "The deck of cards is " << endl;
d.display();
  
d.select();
  
cout << "The deck of cards is " << endl;
d.display();

  
}

output

$ g++ card.cpp deck.cpp main.cpp
$ ./a.out
The deck of cards is
