Create a standard deck of 52 playing cards and list those cards on the screen, columns makes my life easier :-) Pause or "press Enter" after the unshuffled deck is displayed.

"Shuffle" the deck and list the shuffled deck on the screen. random_shuffle from <algorithm> will work on a vector of Cards

Sort (by rank) and evaluate evaluate the first 5 cards of the deck as a 'hand'. Print the unsorted, then the sorted hand.

a pair (say the card rank, like Pair of Queens)

two pair (say something like Pair of Queens and Pair of Twos)

three of a kind (say something like Three Kings)

full house (say something like Full house, Jacks over fours)

straight (say Ace-high straight) A straight is all 5 cards in rank order, ace can be high or low

four of a kind

flush (say something like spades flush)

Ideas:

create a Card class with an internal 'Rank' (A, 2, 3, 4, ..) and 'Suit' (spades, diamonds ...)

Here's one possible idea for a card class (Card.h)

#ifndef CARD_H

#define CARD_H

#include <string>

using namespace std;

class Card
{
    public:
        Card();

        // set and get the rank, 2=2, 3=3, ... 10=10, 11=J, 12=Q, 13=K, 14=A
        void setRank(int r);
        int getRank();

        // set and get the suit, 1=Spades, 2=Hearts, ...
        void setSuit(int r);
        int getSuit();

        // for debugging, print the suit and rand as integers
        void print();

        // return the rank and suit as a 'nice' looking string
        string toString();

        // if you want to use sort() in the STL
        bool operator<(const Card &c) const {return myRank < c.myRank;}

    private:
        int myRank;
        int mySuit;
};

#endif // CARD_H

If you want to use the builtin sort alogrithm with the above class, use:

    vector<Card> hand;

    /// make sure to put cards in the hand here!

    sort(hand.begin(), hand.end());

A=0;
x=0;
n=input('How many variables=');
disp('Enter the coefficients along with constants For instance if x+y+3z=-5 then enter 1 1 3 -5 each number followed by an enter not space');
for i=1:n
   for j=1:n+1
       A(i,j)=input('');
   end
end
%pivoting
for i=1:n-1
   for j=i+1:n
       if abs(A(j,i))>abs(A(i,i))
           T=A(j,:);
           A(j,:)=A(i,:);
           A(i,:)=T;
       end
   end
end
disp('After pivoting');
disp(A);
for k=1:n-1
   for i=k+1:n
       m=A(i,k)/A(k,k);
       for j=k:n+1
           A(i,j)=A(i,j)-m*A(k,j);
       end
   end
end
disp('Triangularize Form ');
disp(A);

if A(n,n)==0
   disp('No unique solution');
end
   x(n)=A(n,n+1)/A(n,n);
   for j=n-1:-1:1
       sum=0;
   for i=1:n
       sprintf('x%.0f=%.10f',i,x(i))
   end


       for i=1:n-j
           sum=sum+A(j,n+1-i)*x(n+1-i);
       end
       x(j)=(A(j,n+1)-sum)/A(j,j);
   end
