Array Card
C++ array question?
I'm trying to figure out how to store cards in a deck...the only thing I can think of is to store the cards in an array, with each card having a form (value)(suit) such as 6c for six of clubs, and 12h for queen of hearts.
So anyway, if I were to make a header function to shuffle the cards, could I do this:
void shuffle(array deck);
Can you use deck of type array as the parameter for the function, or will that not work?
Absolutely.
Just use the [] delimeter to let the compiler know you're expecting an array pointer:
void shuffle(string[] deck);
Or whatever data type you're using to represent a card.
===
From a design standpoint, I think that using the "6c" format would be kind of problematic, because you then have to parse that token to get the pieces out. What I would suggest is using parallel arrays (there are more complicated structures such as structs, classes, and multidimensional arrays--but I'm assuming this is a beginning programming course so parallel arrays is what you're after).
In other words, keep two arrays of the same size, one that holds the number and one that holds the suit as an integer (1-4).
Consider this:
const int DECK_SIZE = 52;
int value[DECK_SIZE];
int suit[DECK_SIZE];
// function prototype
void shuffle(int[], int[]);
// store card 0 in the deck
value[0] = 12;
suit[0] = 3;
// function invocation:
shuffle(value, suit);
// function definition
void shuffle(int[] value, int[] suit) {
// shuffle here
}
Now you could store a value (1-13) in the value array, and a suit (1-4) in the suit array. If you want to be really fancy you could make an enumeration for the suit array, but that's up to you.
