编写演讲比赛评分程序，假定有10个选手，5个评委，选手的得分是去掉一个最高分和一个最低分的平均分。计算出每个选手的平均分，并按从高分到低分的顺序输出所有选手的得分

#include <stdio.h>

#define PLAYER 10
#define REFEREE 5


float calc_score(float *score, int count)
{
    float sum = 0;
    int i, j, tmp;
    /* 冒泡排序(从大到小) */
    for (i = 0; i < count - 1; i++) {
        for (j = i + 1; j < count; j++) {
            if (score[i] < score[j]) {
                tmp = score[i];
                score[i] = score[j];
                score[j] = tmp;
            }
        }
    }
    /* 平均分 */

        player_score[i].number = i + 1;
