for (School school : schools) { if (school.year == year) { cout << "编号：" << school.id << endl; cout << "名称：" << school.name << endl; cout << "地址：" << school.address << endl; cout << "省份：" << school.province << endl; cout << "建校年份：" << school.year << endl; } }修改这段代码能在编译器使用的是 C++98 标准

可以将 range-based for 循环改写成传统的 for 循环，如下所示：

for (vector<School>::iterator it = schools.begin(); it != schools.end(); ++it) {
    School school = *it;
    if (school.year == year) {
        cout << "编号：" << school.id << endl;
        cout << "名称：" << school.name << endl;
        cout << "地址：" << school.address << endl;
        cout << "省份：" << school.province << endl;
        cout << "建校年份：" << school.year << endl;
    }
}

这样就可以在 C++98 标准下编译通过。注意，在传统的 for 循环中，需要使用迭代器来访问容器中的元素，同时需要使用一个变量来存储每个元素的值。

cout<<"school:" << Student::school

cout是C++中的输出流对象，用于向控制台数据。"<<"是流插入运算符，用于将右侧的数据插入到左侧的流对象中。

Student::school是一个静态成员变量，表示学生的学校。静态成员变量属于类，而不属于类的实例对象。可以通过类名和作用域解析运算符::来访问。

所以，cout<<"school:" << Student::school的意思是将字符串"school:"和Student类的静态成员变量school的值一起输出到控制台。

可能是因为加载参赛队伍信息时，有些行的学校名称与你输入的学校名称不完全一致，导致无法找到对应的参赛队伍。

你可以尝试修改 `searchBySchool` 函数，使用字符串的 `find` 函数来判断参赛队伍的学校名称中是否包含输入的字符串，从而实现模糊匹配。具体代码如下：

// 按学校查询参赛队伍信息
void searchBySchool(const vector<Team>& teams) {
    string school;
    cout << "请输入要查询的学校名称：" << endl;
    cin >> school;
    bool found = false;
    for (const auto& team : teams) {
        if (team.school.find(school) != string::npos) {
            cout << "编号：" << team.id << endl;
            cout << "名称：" << team.name << endl;
            cout << "学校：" << team.school << endl;
            cout << "类别：" << team.category << endl;
            cout << "参赛者：" << team.players << endl;
            cout << "教练姓名：" << team.coach << endl;
            found = true;
        }
    }
    if (!found) {
        cout << "无法找到包含 " << school << " 的参赛队伍，请检查输入是否正确！" << endl;
    }
}

这样就可以实现模糊匹配，查找到包含输入的字符串的参赛队伍了。
