如果总和要高于 21，我需要帮助更改 21 点中 ace 的整数值，C

Question

在我的 21 点游戏中，ace 的整数值固定为 11，但在这种情况下，当一名玩家获得 ace 但她手中的牌的总价值将高于 21 我想要整数值王牌是 1.

void deal(const Card * const Deck, int value, int size, int size_1, int size_2){

int i, j, length;
char anotherCard[2];
char name1[30];
char name2[30];
int valueName1 = 0, valueName2 = 0, valueDealer = 0;

printf("Name player one > ");
scanf("%s", name1);
printf("Name player two > ");
scanf("%s", name2);

printf("\nWelcome %s and %s, lets begin!\n\n", name1, name2);
getchar();

while (valueName1 < 21 || valueName2 < 21 || valueDealer < 17){
    printf("%s's card:\n", name1);
    for (i = 0; i < size; i++){
        printf("%5s of %-8s%c", Deck[i].decks, Deck[i].suits, (i + 1) % 2 ? '\t' : '\n');


    if (valueName1 > 21 && Deck[i].value == 11){
        Deck[i].value = 1;                          //error on this line
        valueName1 += Deck[i].value;
        printf("value > %d\n", valueName1);
        }
    else{
        printf("value > %d\n", valueName1);
        }
    }


int main(void){

Card allCards[52];
Card cardValue[52];
char *suitname[] = { "spades", "hearts", "diamonds", "clubs" };
char *deckname[] = { "ace", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "jack", "queen", "king" };
int cardvalue[] = { 11, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10 };



void fillDeck(Card * const Deck, const char *suit[], const char *deck[], const int value[]){

int s;

for (s = 0; s < 52; s++){
    Deck[s].suits = deck[s % 13];
    Deck[s].decks = suit[s / 13];
    Deck[s].value = value[s % 13];
}

return;
}

我的结构：

typedef struct card{
    const char *suits;
    const char *decks;
    int value;
};

错误信息：错误 C2166：左值指定常量对象

Answer 1

您声明 Deck 为

const Card * const Deck

这意味着 Deck 是指向常量数据的常量指针，即您无法更改指针，并且（更重要的是）您无法更改它指向的数据。您需要删除第一个 const 才能使其正常工作

Card * const Deck
