#include <stdio.h>int main() { FILE *fp_score = fopen("score.txt", "r"); FILE *fp_result = fopen("result.txt", "w"); int score, sum = 0, count = 0, max = 0, min = 100; while (fscanf(fp_score, "%d", &score) != EOF) { sum += score; count++; if (score > max) { max = score; } if (score < min) { min = score; } } double average = (double)sum / count; fprintf(fp_result, "%.2lf %d %d", average, max, min); fclose(fp_score); fclose(fp_result); return 0;}这段代码无法实现功能，请修改这段代码

首先，需要检查文件是否成功打开。其次，在写入结果文件时，需要加上换行符，以免多次运行时结果叠加在一行中。最后，为了保证程序的可移植性，应该使用标准的文件路径分隔符（如"/"或"\"）。

修改后的代码如下：

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

int main() {
    FILE *fp_score = fopen("score.txt", "r");
    FILE *fp_result = fopen("result.txt", "w");
    if (fp_score == NULL || fp_result == NULL) {
        printf("Failed to open file!\n");
        exit(1);
    }
    int score, sum = 0, count = 0, max = 0, min = 100;
    while (fscanf(fp_score, "%d", &score) != EOF) {
        sum += score;
        count++;
        if (score > max) {
            max = score;
        }
        if (score < min) {
            min = score;
        }
    }
    double average = (double)sum / count;
    fprintf(fp_result, "%.2lf\n%d\n%d\n", average, max, min);
    fclose(fp_score);
    fclose(fp_result);
    return 0;
}
