c - 排序贪婪高分(文件 I/O)

Question

我正在用 C 实现 Greed(greedjs.com)。我如何将这些数据从最高到最低排序，以及如何附加仅符合前十名玩家资格的分数？

Here's它看起来像什么。

这是我到目前为止的代码:

void high_scores() {
    int c;
    char player_name[256];
    FILE * fhigh_score;
    fhigh_score = fopen("HIGH SCORES.txt", "a");
    if (fhigh_score == NULL) {
        printf("Error");
        exit(1);
   }
   printf("Your Name:\t");
   fgets(player_name, 256, stdin);
   player_name[strlen(player_name) - 1] = 0;
   fprintf(fhigh_score, "\t%s\t%d\n", player_name, SCORE);
   fclose(fhigh_score);

   fhigh_score = fopen("HIGH SCORES.txt", "r");
   if (fhigh_score == NULL) {
       printf("Error");
       exit(1);
   }
   else if (fhigh_score) {
       while ((c = getc(fhigh_score)) != EOF)   //print file to terminal
       putchar(c);
       fclose(fhigh_score);
   }
}

Answer 1

您需要的是一个数据结构来存储玩家及其得分。例如:

struct Player {
    const char* name;
    int score;
};

然后您可以创建一个此类结构的数组，将文件中的所有玩家数据放在那里，然后应用qsort()对其进行排序。您还需要一个比较函数来按得分对玩家进行排序，以提供给 qsort。
