5 カード ポーカー ゲームを作成していますが、デバッガーでプログラムを実行するとエラーが発生し続けます。

このコードをデバッガーで 8 回実行しましたが、そのうち 5 回エラーが発生しました — コードを一切変更していません。ときどき文字列を正しく読み取れない原因は何ですか? 私がそれを理解するのを手伝ってください。

必要なコード:

-初期化

char *suit[4] = {"Hearts", "Diamonds", "Clubs", "Spades"};
char *face[13] = {"Ace", "Two", "Three", "Four", "Five", "Six", "Seven", 
"Eight", "Nine", "Ten", "Jack", "Queen", "King"};
Card p1_hand[5] = {{0,0,0}};

-メインの関数呼び出し

print_hand(face, suit, p1_hand);

-ヘッダーファイル内の関数 // Card 構造体

typedef struct card
{
int card_number;
int face_index;
int suit_index;
} Card;

void print_hand (char *face[4], char *suit[13], Card p1_hand[5]);

・機能そのもの

void print_hand (char *face[], char *suit[], Card p1_hand[5])
{
int i = 0, j = 0, k = 0;

printf("You're hand:\n");
for(i = 0; i < 5; i++)
{
    j = p1_hand[i].face_index;
    k = p1_hand[i].suit_index;
    printf("%d: %5s of %-8s\n", (i+1), face[j], suit[k]);
}
}

最初のprintfの前にデバッガーの停止ポイントを置き、時々これを取得します

  • face 0x0040fb5c {0x0000000a Error reading characters of string.}

しかし、コードをまったく変更せずにこれを取得する場合もあります

  • face 0x002afe40 {0x013a787c "Ace"} （どちらが正しい）

これを理解するのを手伝ってください！それは私を夢中にさせています。

コメントには少し大きいため、CWの回答です。

void print_hand(char *face[], char *suit[], Card p1_hand[5])
{
    printf("Your hand:\n");
    for (int i = 0; i < 5; i++)
    {
        int j = p1_hand[i].face_index;
        int k = p1_hand[i].suit_index;
        printf("--DEBUG--: %d %d %d\n", p1_hand[i].card_number, j, k);
        printf("%d: %5s of %-8s\n", (i+1), face[j], suit[k]);
    }
}

p1_handこれにより、データを使用する前にの各エントリのデータが出力されます。これは、何が起こっているかについて何かを教えてくれるかもしれません。代替または追加としてアサーションを追加できます。

        assert(j >= 0 && j < 13);
        assert(k >= 0 && j < 4);

良いニュースは、shuffle()機能が問題ないように見えることです。
