C 中的垃圾游戏

Question

我正在尝试制作一个掷骰子游戏，其中会掷骰子来检查它是否命中目标。我不能确定我的 while 循环有什么问题，但即使 while 循环要求为假，它也会保持运行。这是我的代码：

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

int rollDice() {
    int sum, d1, d2;
    sum = 0;
    d1 = (rand() % 6) + 1;
    d2 = (rand() % 6) + 1; 
    sum = d1 + d2;
    printf("Player rolled %d + %d = %d\n", d1, d2, sum);
    return sum;
}

int main() {
    int player, target, tries;
    srand(time(NULL));
    tries = 0;
    player = rollDice();
    target = player;
    if (player == 7 || player == 11) {
        printf("Player wins.\n");
    }
    else if (player == 2 || player == 3 || player == 12) {
        printf("Player loses.\n");
    } else {
        printf("Point is %d. The game continues: \n", target);
        player = rollDice();
    }
    printf("Player is %d, Target is %d.\n", player, target);
    while (target != player || player != 7) {
        player = rollDice();
    }
    return 0;
}

当掷出 7 或再次掷出玩家分数时，游戏结束。因此 while 测试应该是 while (target != player && player != 7)，而不是 while (target != player || player != 7).

您还必须将 while 循环移动到最后一个 else 块中。

这是修改后的版本：

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

int rollDice(void) {
    int sum, d1, d2;
    sum = 0;
    d1 = rand() % 6 + 1;
    d2 = rand() % 6 + 1; 
    sum = d1 + d2;
    printf("Player rolled %d + %d = %d\n", d1, d2, sum);
    return sum;
}

int main() {
    int player, target, tries;
    srand(time(NULL));
    tries = 0;
    player = rollDice();
    target = player;
    if (player == 7 || player == 11) {
        printf("Player wins.\n");
    } else
    if (player == 2 || player == 3 || player == 12) {
        printf("Player loses.\n");
    } else {
        printf("Point is %d. The game continues:\n", target);
        player = rollDice();

        printf("Player is %d, Target is %d.\n", player, target);
        for (;;) {
            if (player == 7) {
                printf("Pass loses\n");
                break;
            }
            if (player == target) {
                printf("Pass wins\n");
                break;
            }
            player = rollDice();
        }
    }
    return 0;
}
