c - 掷骰子游戏

Question

我试图让用户输入 y 或 n，游戏将退出或继续。我还想显示总输赢和用户退出。也许我没有真正掌握 boolean 值并返回函数中的东西？

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

int rollDice(void);
bool playGame(void);

int main(void)
{
    srand((unsigned)(time(NULL)));
    char userInput;
    while (true)
    {
        playGame();
        printf("Would you like to play again?");
        scanf("%c", &userInput);
        if (userInput == 'n' || userInput == 'N')
        {
            return false;
        }
        else
        {
            return true;
        }
    }
    return 0;
}
int rollDice(void)
{

    int dice1 = rand()%6+1;
    int dice2 = rand()%6+1;
    int totaldice = dice1 + dice2;

    return totaldice;
}
bool playGame(void)
{
    int point, total;
    int winCounter, looseCounter;
    printf("The game is starting!\n");
    total = rollDice();
    printf("You rolled: %d\n", total);
    if (total == 7 || total == 11)
    {

        printf("Wow it's your lucky day! You Win!\n");
        winCounter++;

    }
    else if (total == 2 || total == 3 || total == 12)
    {
        printf("Unlucky! You Loose!\n");
        looseCounter++;
    }
    else {
        point = total;
        printf("Your Point is: %d\n", point);
        while (true)
        {
            total = rollDice();
            printf("You rolled: %d\n", total);
            if (total == point)
            {
                printf("You made your point! You Win!\n");
                winCounter++;
                break;
            }
            else if (total == 7)
            {
                printf("Thats a %d. You Loose!\n", total);
                looseCounter++;
                break;
            }
        }

    }return true;
}

Answer 1

您的主要问题是，如果用户输入的内容与 'n' 或 'N' 不同，您会使用 return 终止 main指令。删除它，循环可以继续。

如果使用 boolean 变量退出 while 循环会更好:

int main(void)
{
    srand((unsigned)(time(NULL)));
    char userInput;

    bool paygame = true;

    while (paygame)
    {
        playGame();
        printf("Would you like to play again?");
        scanf(" %c", &userInput);

        printf ("Test: %c\n", userInput);
        if (userInput == 'n' || userInput == 'N')
        {
            paygame = false;
        }
    }
    return 0;
}

第二个大问题是 playgame 函数的计数器:它们必须初始化为 0。

int winCounter = 0, looseCounter = 0;

否则从随机数开始计数。

如果你想计算所有玩过的游戏的所有输赢，你可以简单地使用静态变量:

bool playGame(void)
{
    int point, total;
    static int winCounter = 0, looseCounter = 0;
    printf("The game is starting!\n");
    total = rollDice();
    printf("You rolled: %d\n", total);
    if (total == 7 || total == 11)
    {

        printf("Wow it's your lucky day! You Win!\n");
        winCounter++;

    }
    else if (total == 2 || total == 3 || total == 12)
    {
        printf("Unlucky! You Loose!\n");
        looseCounter++;
    }
    else {
        point = total;
        printf("Your Point is: %d\n", point);
        while (true)
        {
            total = rollDice();
            printf("You rolled: %d\n", total);
            if (total == point)
            {
                printf("You made your point! You Win!\n");
                winCounter++;
                break;
            }
            else if (total == 7)
            {
                printf("Thats a %d. You Loose!\n", total);
                looseCounter++;
                break;
            }
        }

    }

    printf ("Won: %d - Lose: %d\n", winCounter, looseCounter);

    return true;
}

最后一件事是将 scanf 格式说明符更改为 "%c" 以允许 scanf “刷新”换行符 '\n ' 字符在用户每次输入后留在 stdin 中。
