// draw 5 cards each from a standard deck of cards (52 cards; 4 suits,
// 13 faces).
// Compile instructions:

#include <iostream>
#include <cstdlib>
#include <ctime> // library used to re-seed the rand() function
#include <iomanip>

// function prototype that initializes all the elements of
// the array to zero.

char faces[13][10] = {"ACE","K","Q","J","10","9","8","7","6","5","4","3","2"};

// NOTE: Could store user's cards in an array of 5x2 elements: 5 cards
// and [i][0] would store face value of i'th card, and [i][1] suitvalue
// BUT, by storing in same way that are keeping track of the cards in the
// deck that have been dealt, might be easier to 'rank' the cards?
