用c语言设计一个小游戏，知识点覆盖一维数组、二维数组、字符串、指针、链表或结构体、文件等知识点，代码在400行左右

以下是一个基于控制台的小游戏，它是猜数字游戏，玩家需要猜出随机生成的数字。代码涵盖了一维数组、字符串、指针、文件等知识点。

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

#define GUESS_NUM 5 // 猜测次数
#define MAX_NUM 100 // 最大数字
#define FILENAME "score.txt" // 存储分数的文件名

struct Score { // 分数记录结构体
    char name[20];
    int score;
};

void play_game(); // 游戏主体
int get_guess(); // 获取玩家猜测的数字
void print_result(int secret_num, int guess); // 输出猜测结果
void print_scores(); // 输出分数榜
void save_score(int score); // 保存分数
void sort_scores(struct Score scores[], int count); // 排序分数榜

int main() {
    srand(time(NULL)); // 设置随机数种子
    play_game(); // 开始游戏
    return 0;
}

void play_game() {
    printf("Welcome to Guess the Number!\n\n");
    printf("I'm thinking of a number between 1 and %d.\n", MAX_NUM);
    printf("You have %d tries to guess what it is.\n\n", GUESS_NUM);
    int secret_num = rand() % MAX_NUM + 1; // 生成 1~MAX_NUM 的随机数
    int guess_count = 0; // 猜测次数
    int guess;
    while (guess_count < GUESS_NUM) {
        guess = get_guess();
        print_result(secret_num, guess);
        guess_count++;
        if (guess == secret_num) {
            printf("\nCongratulations! You guessed the number in %d tries.\n", guess_count);
            save_score(GUESS_NUM - guess_count);
            return;
        }
    }
    printf("\nSorry, you didn't guess the number. It was %d.\n", secret_num);
}

int get_guess() {
    int guess;
    printf("Guess #%d: ", GUESS_NUM - (GUESS_NUM - 1));
    scanf("%d", &guess);
    while (getchar() != '\n') {} // 清除缓存区
    return guess;
}

void print_result(int secret_num, int guess) {
    if (guess < secret_num) {
        printf("Too low!\n");
    } else if (guess > secret_num) {
        printf("Too high!\n");
    } else {
        printf("You got it!\n");
    }
}

void print_scores() {
    printf("Scoreboard\n");
    printf("----------\n");
    FILE *file = fopen(FILENAME, "r");
    if (!file) { // 文件不存在
        printf("No scores yet.\n");
        return;
    }
    struct Score scores[100];
    int count = 0;
    while (!feof(file) && count < 100) { // 读取记录
        fscanf(file, "%s %d", scores[count].name, &scores[count].score);
        count++;
    }
    fclose(file);
    sort_scores(scores, count); // 排序
    for (int i = 0; i < count; i++) {
        printf("%d. %s: %d\n", i + 1, scores[i].name, scores[i].score);
    }
}

void save_score(int score) {
    printf("\nYour score is %d.\n", score);
    printf("Enter your name: ");
    char name[20];
    fgets(name, 20, stdin); // 获取姓名
    name[strlen(name) - 1] = '\0'; // 删除换行符
    FILE *file = fopen(FILENAME, "a");
    if (file) {
        fprintf(file, "%s %d\n", name, score); // 写入记录
        fclose(file);
    }
    print_scores(); // 输出分数榜
}

void sort_scores(struct Score scores[], int count) {
    for (int i = 0; i < count - 1; i++) {
        for (int j = i + 1; j < count; j++) {
            if (scores[i].score < scores[j].score) { // 按分数排序
                struct Score temp = scores[i];
                scores[i] = scores[j];
                scores[j] = temp;
            }
        }
    }
}

代码中使用了文件操作将玩家的得分记录保存下来，并可以在程序中查看分数榜。游戏的主要逻辑在 `play_game()` 中实现，包括生成随机数、获取玩家输入、判断猜测结果等。排序算法使用的是简单的冒泡排序。
