所以我尝试用 C 语言编写一个 Blackjack 游戏只是为了好玩（这是我以前从未尝试过的）。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（显示庄家只有 1 张牌，而应该显示 2 张牌）。这是一个屏幕截图：
我确实在我的手机上运行了这个（更容易获得截图），但我在我的计算机上使用 Code::Blocks 得到了相同的结果。无论如何，我有两个函数来处理设置套牌和显示当前卡片。我在 main() 函数中使用循环处理的牌。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);
