Fgets无故被跳过

Question

我的代码不工作，由于某些原因，它跳过了一个 "fgets "指令，我一直在不厌其烦地试图解决这个问题，但我不能。我正在做一个简单的C游戏，关于掷3个骰子，并给出结果，玩家会比猜测下一个结果是更高，更低还是与上一个相同。

下面是代码。

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <string.h>

int main(int argc, char *args[]) {
    printf("__________________________OPEN THE GAME!_________________________\n");
    printf("\tThe rules are simple,\n\twe are gonna roll 3 dices and\n\tgive you the result.\n\tYou're then going to guess if\n\tthe next roll is gonna be\n\thigher(h), lower(l) or same(s)!\n");
    //char ready[3];
    //printf("\t\t\tAre you ready? ");
    //fgets(ready, 2, stdin);

    int roll1;

    int roll2;

    int roll3;

    char enter[] = "y";

    while(strcmp(enter, "n")) 
    {
        roll1 = rand()%6 + 1;
        roll2 = rand()%6 + 1;
        roll3 = rand()%6 + 1;
        printf("First roll!\n%d\n\n", roll1);
        printf("Second roll!\n%d\n\n", roll2);
        printf("Third roll!\n%d\n\n", roll3);

        int firstResult = roll1 + roll2 + roll3;
        printf("Result: %d\n", firstResult);

        char guess[2];
        printf("\t\t\tWill the next one be h/l/s? ");
        fgets(guess, 2, stdin);

        int result = (rand()%6 + 1) + (rand()%6 + 1) + (rand()%6 + 1);

        if (((result == firstResult) && (strcmp(guess,"s"))) || ((result > firstResult) && (strcmp(guess,"h"))) || ((result < firstResult) && (strcmp(guess,"l"))))
        {
            printf("°°°°°°°°°°°Correct, you win!°°°°°°°°°°°\n");
            printf("      The result was: %d\n", result);
        }
        else
        {
            printf("\tI'm sorry, the new roll is %d :(\n", result);
        }

        printf("\tTry again?(y/n)");
        fgets(enter, 2, stdin);

        firstResult = result;
    }
    printf("\t\t\tGG, come back when you want to test your luck B)\n");
    return 0;
}

fgets指令被跳过，在底部，在再试一次之后. 谁能解释一下，我漏掉了什么? 即使用scanfs也不行，或者用char代替字符串.

Answer 1

fgets() 缓冲区太小。

输入 "h\n" 至少需要3个才能完全保存为一个字符串。

使用更大的缓冲区。

读取后，用 fgets()，切断潜在的 '\n' 做出以下决定 strcmp(guess,"s") 工作。

    char guess[100];
    printf("\t\t\tWill the next one be h/l/s? ");
    fgets(guess, sizeof guess, stdin);
    guess[strcspn(guess, "\n")] = '\0';

需要进行类似的改变 fgets(enter...
