c - C中的循环猜谜游戏

Question

让用户猜测程序选择的幸运数字的程序。它使用一个 for 循环和大量的 if 语句。问题是我的代码在 2 次尝试后停止，但假设给用户 3 次尝试。这是我目前所拥有的:

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

int main()
{
    int iSecret, iGuess;
    srand(time(NULL));
    iSecret = rand() % 20 + 1;
    int tries = 0;

    printf("\nWelcome to the number guessing game!\nFor each game, you have at most 3 chances to guess a secret number from 1 to 20.\n");

    for (tries = 0; tries < 3 || iSecret == iGuess; tries++)
    {
        printf("Please, enter a number between 1 and 20!   ");
        scanf("%d", &iGuess);

        if (iGuess == iSecret)
        {
            printf("\nCongratulations! You won!");
            return 0;
        }

        else if (iGuess > iSecret)
        {
            tries++;
            printf("\nYour guess was too high.\n");
        }

        else if (iGuess < iSecret)
        {
            tries++;
            printf("\nYour guess was too low.\n");
        }
        if (tries == 3)
            break;
    }

    printf("\nYou have reached your third trials. The correct number is %d.\n",
            iSecret);
    return 0;
}

Answer 1

您正在递增 tries 两次:一次是在 for 定义中，另一次是在循环体中。

删除多余的 tries++ 语句。
