运动会成绩管理系统c++

以下是一个简单的运动会成绩管理系统的C++代码，实现了基本要求中的功能：

#include <iostream>
#include <fstream>

#include <vector>
#include <algorithm>

    int female_score; // 女子团体总分
    vector<int> male_scores; // 男子项目成绩
    vector<int> female_scores; // 女子项目成绩
};

// 定义项目结构体

    int score3[3]; // 前三名积分
    vector<int> schools[5]; // 前五名学校编号
    vector<int> schools3[3]; // 前三名学校编号

// 定义全局变量
vector<School> schools; // 学校列表

// 比较函数，用于排序
