c - C Blackjack 游戏的 int 数组缺少输出

Question

所以我尝试用 C 语言编写一个二十一点游戏只是为了好玩(我以前从未尝试过)。我已经完成了最初的几个步骤，例如如何设置牌组以及如何将牌交给庄家和玩家。但是，显示的输出也没有显示我想要的内容(显示庄家只有 1 张牌，而它应该显示 2 张)。这是屏幕截图:

我确实在手机上运行了这个(更容易获得屏幕截图)，但我使用 Code::Blocks 在计算机上得到了相同的结果。不管怎样，我有两个函数来处理设置牌组和显示当前的牌。我在 main() 函数中使用循环处理牌。我知道 makeDeck() 函数工作正常，所以我假设我的错误在其他地方。看看我的代码，让我知道发生了什么(另外，任何改进建议将不胜感激):

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

/*Function Prototypes*/
int* makeDeck();
    /*Usage - returns an int* to be used for the deck */

void showHands(int[], int[]);
    /*Usage - pass dealerHand[], then playerHand[] */

int main() {
        srand(time(0));     //Make a new rand() seed value
    int  x, count = 0, choice = 1;
    int* cards        = makeDeck();
    int  dealerCards[12];       //cards in hand will never exceed 11
    int  playerCards[12];       //4 A's, 4 2's, 3 3's

    /*Loop to run the game. One iteration per hand */
    while(choice != 0) {
        for(x = 0; x < 12; x++) {
            dealerCards[x] = 0;
            playerCards[x] = 0;
        }

        //Deal 2 cards to dealer and player
        for(x = 0; x < 2; x++) {
            dealerCards[x] = cards[count];
            count++;
        }
        for(x = 0; x < 2; x++) {
            playerCards[x] = cards[count];
            count++;
        }

        showHands(dealerCards, playerCards);

        printf("\nEnter 0 to exit loop: ");
        scanf("%i", &choice);

您的 for 循环似乎相互包含。

for(x = 0; x < 12; x++) {
  if(dealer[x] != 0) {
    ...
  }
  puts("\nPlayer: ");
  for(x = 0; x < 12; x++) {
    ...
  }
}

第一个 for 循环从 x = 0 开始，第二个 for 循环上升到 x = 12，然后第一个 for 循环在第二次执行之前停止，因为它达到了终止条件。
