使用c语言编程 参加运动会有 n 个学校，学校编号为....比赛分成 m 个男子 项目，和 w 个女子项目。项目编号为男子 1....m.女子 m....mn+w.不同的项目取前五名或前三名积分:取前五名的 积分分别为: 7. 5、3、2、1,前三名的积分分别为: 5、3、2; 哪些取前五名或前三名由学生自己设定。(m<=20, n<=20) [任务要求] 功能要求: 1). 可以输入各个项目的前三名或前五名的成绩； 2).能统计各学校总分； 3).可以按学校编号、学校总分、男女团体总分排序输出； 4).可以按学校编号查询学校某个项目的情况:可以按项目编 号查询取得前三或前五名的学校 规定:输入数据形式和范围: 20 以内的整数(如果做得更好可 以输入学校的名称，运动项目的名称) 输出形式:有中文提示，各学校分数为整型。

这个题目比较复杂，需要使用结构体和排序算法来实现。以下是一个简单的实现，仅供参考：

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

#define MAX_SCHOOLS 20
#define MAX_PROJECTS 40
#define MAX_NAME_LENGTH 20

typedef struct {
    int id;
    char name[MAX_NAME_LENGTH];
    int scores[MAX_PROJECTS][5]; // 前五名成绩
    int total_score;
    int male_score;
    int female_score;
} School;

School schools[MAX_SCHOOLS];
int num_schools, num_male_projects, num_female_projects;

// 比较函数，用于排序
int cmp(const void* a, const void* b) {
    School* s1 = (School*)a;
    School* s2 = (School*)b;
    if (s1->total_score != s2->total_score) {
        return s2->total_score - s1->total_score;
    } else if (s1->male_score != s2->male_score) {
        return s2->male_score - s1->male_score;
    } else if (s1->female_score != s2->female_score) {
        return s2->female_score - s1->female_score;
    } else {
        return s1->id - s2->id;
    }
}

// 查询学校某个项目的前三或前五名
void query_project(int project_id, int top_num) {
    printf("请输入项目 %d 的前 %d 名成绩：\n", project_id, top_num);
    for (int i = 0; i < num_schools; i++) {
        printf("学校 %d (%s)：\n", schools[i].id, schools[i].name);
        for (int j = 0; j < top_num; j++) {
            scanf("%d", &schools[i].scores[project_id][j]);
        }
    }
}

// 统计各学校总分、男女团体总分
void calculate_scores() {
    for (int i = 0; i < num_schools; i++) {
        schools[i].total_score = 0;
