用c语言和easyx编写游戏:输入游戏者名字：该名字用于显示在游戏界面上，并在通关后记录该游戏者的得分数，将用户名和得分数记录到highscore.dat文件中，并倒序显示得分最高的前十名信息。

这个任务需要用到 C 语言的文件操作和 EasyX 绘图库，下面是一个简单的实现：

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

#define MAX_NAME_LEN 20  // 最大名字长度
#define MAX_SCORES 10    // 最多记录的得分数

typedef struct {
    char name[MAX_NAME_LEN + 1]; // 游戏者名字
    int score;                   // 得分数
} Player;

void save_score(Player* players, int num_players) {
    FILE* fp = fopen("highscore.dat", "wb");
    if (fp == NULL) {
        printf("Error: cannot open file!\n");
        exit(1);
    }
    fwrite(players, sizeof(Player), num_players, fp);
    fclose(fp);
}

int compare_scores(const void* p1, const void* p2) {
    Player* player1 = (Player*)p1;
    Player* player2 = (Player*)p2;
    return player2->score - player1->score; // 倒序排列
}

void draw_high_scores(Player* players, int num_players) {
    cleardevice();
    settextstyle(32, 0, "宋体");
    outtextxy(100, 50, "得分最高的前十名：");
    int y = 100;
    for (int i = 0; i < num_players; i++) {
        char text[100];
        sprintf(text, "%d. %s: %d 分", i+1, players[i].name, players[i].score);
        outtextxy(100, y, text);
        y += 50;
    }
}

int main() {
    initgraph(640, 480);
    char name[MAX_NAME_LEN + 1];
    printf("请输入游戏者名字：");
    scanf("%s", name);
    Player player = { .score = 100, .name = name }; // 假设得分为 100
    Player players[MAX_SCORES];
    int num_players = 0;
    FILE* fp = fopen("highscore.dat", "rb");
    if (fp) {
        num_players = fread(players, sizeof(Player), MAX_SCORES, fp);
        fclose(fp);
        qsort(players, num_players, sizeof(Player), compare_scores);
    }
    int i;
    for (i = 0; i < num_players; i++) {
        if (player.score > players[i].score) {
            break;
        }
    }
    if (i < MAX_SCORES) {
        for (int j = num_players-1; j >= i; j--) {
            players[j+1] = players[j];
        }
        players[i] = player;
        num_players++;
        if (num_players > MAX_SCORES) {
            num_players = MAX_SCORES;
        }
        save_score(players, num_players);
    }
    draw_high_scores(players, num_players);
    getch();
    closegraph();
    return 0;
}

这个程序首先让用户输入游戏者名字，然后读取 highscore.dat 文件中已有的得分记录，并按得分倒序排列。然后将新的得分记录插入到合适的位置，保存到文件中。最后在屏幕上绘制前十名得分的信息。
