QUESTION
code I am trying to remove cards with the same color and number from total cards but I am having trouble making conditions for my for loop
...ANSWER
Answered 2021-Jun-14 at 02:51Okay, since there are some things about your question that are not very clear, I am going to assume what seems reasonable and answer with that in mind. My assumptions are:
- When there is a match of number and color, both cards should be removed;
- If there are repeated cards (same color and number), all of their instances should be removed.
So, first, I believe in order to make the comparisons easier to understand and more efficient, we can make a specific function to tell us the color of the card based on its suit. This will make your conditions much cleaner:
QUESTION
We consider a deck of playing cards in the following format:
Ranks: 2, 3, 4, 5, 6, 7, 8, 9, T, J, Q, K, A
Suits: S - Spade, D - Diamond, H - Heart, C - Club
Every card will be identified by 2 characters
E.g. "3S" (3 of Spades), "TC" (10 of Club), "AH" (Ace of Heart). I want to modify the getCardsBySuit method in order to return a Stream with all the cards belonging to that suit.
E.g. for a list that contains "2H", "3S", "TH" and the suit is 'H', the result should be a stream containing "2H" and "TH"
...ANSWER
Answered 2021-May-31 at 14:18Assuming all elements in cards have atleast 2 characters and the suit is at second position.
QUESTION
I have built a simple "Higher or Lower" card game for two players using reference from Why is the same card being drawn in this while loop for card deck?. The game flow should be like this:
- First player (Computer) to draw a card from the deck and show it
- Each player place a guess whether the next card drawn will be higher or lower in value to the first card drawn
- The second player (Player_1) draw a card and show it
- Whoever guess is correct will get one point
- After the last card of the deck is drawn, the points are to be tallied

QUESTION
I am new to Swift, but I am trying to make a simple blackjack game. I have a HIT button that adds a card to the player's hand and increases the player's total score each time. But I also want to add a condition to the HIT button that if the player's total is over 21 a new screen appears with the text "You lose". However, I cannot get the button to open another view.
I at first thought to change the HIT button to a NavigationView but then I couldn't figure out where to add the ifBust condition, so I thought it would better solution to make a new .swift file and call the file name in the if statement, that does not seem to work either.
I have a isBust function that returns true if the player's score is over 21:

Answered 2021-May-27 at 20:47I think I figured out the answer to my own question. First I need to add a selection variable with nil (also meaning null?) as its value within the file.

CARD cards[52];
void initializeCards() {
char* types[10] = {"Spade", "Club", "Hearts", "Diamonds"};

cards[i*13 + e].type = types[i];
cards[i*13 + e].value = values[e];

//Code in this function comes from this thread: https://stackoverflow.com/questions/34844003/changing-array-inside-function-in-c

void shuffleArray(char** array, uint8_t size) {
free(*array);
*array = malloc(size * sizeof(int));
//char* temp = (*array)[0];
//(*array)[0] = 1;
(*array)[0] = "test";
printf("%s\n", &array[0]);
}//shuffleArray.
ANSWER
Answered 2021-May-19 at 15:47It's not entirely clear what you're trying to do, but you certainly cannot free an array that is not allocated via malloc (and family). Perhaps you want something like:
QUESTION
typedef struct {
char* value;
char* type;
} CARD;
CARD cards[52];
void initializeCards() {
char types[4][10] = {"Spade", "Club", "Hearts", "Diamonds"};
char values[13][1] = {"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "B", "D", "K"};
for (int i = 0; i < 4; i++) {
for (int e = 0; e < 13; e++) {
cards[i*13 + e].type = types[i];
cards[i*13 + e].value = values[e];
}
}
//This prints all sorts of weid characters.
for (int i=0; i<52; i++) {
printf("%s %s\n", cards[i].type, cards[i].value);
}
}//initializeCards.
ANSWER
Answered 2021-May-18 at 14:30Your array values doesn't have enough elements to store the terminating null-character, but you are trying to print that as strings (sequences of characters terminated by a null-character) later.
Allocate enough elements so that the array can hold terminating null-characters.
Wrong line:
QUESTION
I have built a deck of cards in the following code. I'm running a while loop to try drawing cards from the deck, but the same card is repeatedly drawn for the entire length of the deck. Obviously, what I want is to draw a different card each time.
What am I doing wrong?
...ANSWER
Answered 2021-May-16 at 12:10Your show_hand has a loop that exits immediately upon its first iteration, so it just prints the first card and then exits... no matter how many cards are in the hand. So there is no problem with drawing the cards. The problem is in the printing...
Since card.show() prints something, show_hand really shouldn't return anything, and you should just let the loop make all its iterations.
So I would suggest changing it to this:

QUESTION
I am starting with python and I am trying to code a card game where a user and computer play for 5 rounds. User and computer have to get one random card from the deck I created and the winner is the one with the highest card.
I have several problems in my code.
For example, when I create the whole deck I get this output for the "bastos" cards:
"8 de bastos", "9 de bastos", "10 de bastos" and "11 de bastos" instead of "sota de bastos", "caballo de bastos", "rey de bastos" and "as de bastos".
It only happens with "bastos" because it is my first variable in the list. But I do not know how to fix this.
Then I also have a problem with the result:
...ANSWER
Answered 2021-May-11 at 20:46Some issues:
for c in cartawill iterate each character ofcarta. That is not what you intended.- Changing
nafter you have assigned a value tocarta, will not changecarta. - When comparing
carta_humano > carta_ordenador, you are comparing those strings, and so for example "rey" will be regarded greater than "as". You need to compare the numeric values of the cards. - "sotas" must be quoted
I would suggest creating a class for a card, that will be like a tuple with rank and suit properties, and which has a __repr__ method that will take care of generating the "nice" name. By defining it as a tuple, the order is based on the first member (rank), which is what we need.
I would also not shuffle and pick a random card. If you have already shuffled the deck, you can just take the last card. That is just as random as selecting a random one. You put the selected card back on the deck, but in my opinion that is overkill. There are cards enough to play 5 rounds, so don't bother putting them back. But that is just my opinion. It is not essential for your question.
The final elif can be just an else as there is only one possibility left.
Here is how it could work:
QUESTION
I'm building a deck of cards that has shuffling function. I'm using random.shuffle, but it is not shuffling at all. When I run the following codes, the whole deck is printed out in good order. Please have a look, thanks!
...ANSWER
Answered 2021-May-09 at 10:51I just tried your code, the console output messages you are seeing in good order are created from the self.build() function, if you call deck.show() at the end, you will see the shuffled messages.
