c语言实现2 随机抽取一个单词，界面显示该单词的首尾字母以及中间空缺位符，对应的释义，缺失的部分由玩家输入，显示游戏剩余的错误次数，显示出题目的同时开始计时 3 玩家输入完成后，判断其是否正确，当答题剩余3秒时进行提示 4 如果回答正确，则玩家分数加1；如果超时或回答错误，判断为错误，错误剩余次数减1 5 不断重复前面的过程，当剩余错误次数为零时，游戏结束

以下是一个简单的实现：

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

#define WORD_COUNT 5    // 单词数量
#define MAX_WORD_LEN 20 // 最大单词长度
#define MAX_WRONG_GUESSES 5 // 最大错误次数
#define HIDDEN_CHAR '-' // 隐藏字符

const char *WORDS[WORD_COUNT] = {"apple", "banana", "orange", "grape", "peach"};
const char *DEFINITIONS[WORD_COUNT] = {
    "a round fruit with red, green, or yellow skin and a white center",
    "a long curved fruit with a yellow skin",
    "a round fruit with an orange skin and a sweet juice",
    "a small round fruit that is usually purple or green",
    "a fruit with a fuzzy yellow or pink skin and a juicy yellow center"
};

int main()
{
    srand(time(NULL)); // 初始化随机数生成器
    int score = 0; // 玩家得分
    int wrong_guesses = 0; // 错误次数
    clock_t start_time; // 开始时间
    clock_t end_time; // 结束时间
    int word_index = rand() % WORD_COUNT; // 随机选择一个单词
    const char *word = WORDS[word_index];
    const char *definition = DEFINITIONS[word_index];
    int len = strlen(word);
    char hidden_word[MAX_WORD_LEN + 1];
    memset(hidden_word, HIDDEN_CHAR, sizeof(hidden_word));
    hidden_word[0] = word[0];
    hidden_word[len - 1] = word[len - 1];
    printf("Word: %s\n", hidden_word);
    printf("Definition: %s\n", definition);
    start_time = clock(); // 记录开始时间
    while (wrong_guesses < MAX_WRONG_GUESSES)
    {
        printf("Guess a letter or the whole word: ");
        char guess[MAX_WORD_LEN + 1];
        scanf("%s", guess);
        if (strcmp(guess, word) == 0) // 猜对了整个单词
        {
            printf("Correct!\n");
            score++;
            break;
        }
        else if (strlen(guess) == 1) // 猜对了一个字母
        {
            int found = 0;
            for (int i = 1; i < len - 1; i++)
            {
                if (word[i] == guess[0])
                {
                    hidden_word[i] = guess[0];
                    found = 1;
                }
            }
            if (found)
            {
                printf("Correct!\n");
                printf("Word: %s\n", hidden_word);
            }
            else
            {
                printf("Wrong!\n");
                wrong_guesses++;
                printf("You have %d wrong guesses left.\n", MAX_WRONG_GUESSES - wrong_guesses);
            }
        }
        else // 猜错了整个单词
        {
            printf("Wrong!\n");
            wrong_guesses++;
            printf("You have %d wrong guesses left.\n", MAX_WRONG_GUESSES - wrong_guesses);
        }
        if (strcmp(hidden_word, word) == 0) // 猜对了整个单词
        {
            printf("Correct!\n");
            score++;
            break;
        }
        end_time = clock(); // 记录结束时间
        double elapsed_time = (double)(end_time - start_time) / CLOCKS_PER_SEC;
        if (elapsed_time >= 57) // 剩余3秒
        {
            printf("Time is running out!\n");
        }
    }
    printf("Game over! Your score is %d.\n", score);
    return 0;
}

该程序随机选择一个单词，并显示该单词的首尾字母以及中间的空缺字符。玩家需要猜测单词中的字母或整个单词，并在限定的错误次数内猜对。如果猜对了一个字母，程序会显示出现的位置；如果猜对了整个单词，程序会给出正确提示并加分；如果超时或猜错了整个单词，程序会减少错误次数。当错误次数达到最大值时，游戏结束，显示玩家得分。
