解释 cout << "Usage: histogram_matching.exe <image1> <image2>" << endl;

这是一行C++代码，主要功能是输出一条提示信息。具体解释如下：

- `cout`是C++标准库中的输出流对象，用于向控制台输出信息。
- `<<`是C++中的流插入运算符，表示将右侧的内容插入到左侧的输出流中。
- `"Usage: histogram_matching.exe <image1> <image2>"`是要输出的信息，包括了程序的使用方法和需要的参数。
- `endl`是C++中的换行符，表示输出结束后换行。
- 整个代码的作用是输出一条提示信息，告诉用户如何使用该程序。具体内容是：使用`histogram_matching.exe`命令时需要两个参数，分别为`<image1>`和`<image2>`，用于进行直方图匹配。

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。

// 从文件中加载参赛队伍信息 void loadTeamsFromFile(vector<Team>& teams) { ifstream inFile("team.txt"); if (!inFile.is_open()) { cout << "无法打开team.txt文件！" << endl; return; } string line; while (getline(inFile, line)) { stringstream ss(line); Team team; if (ss >> team.id) { ss >> std::ws; getline(ss, team.name, '\t'); ss >> std::ws; getline(ss, team.school, '\t'); ss >> std::ws; getline(ss, team.category, '\t'); ss >> std::ws; getline(ss, team.players, '\t'); ss >> std::ws; getline(ss, team.coach); cout << "id: " << team.id << ", name: " << team.name << ", school: " << team.school << ", category: " << team.category << ", players: " << team.players << ", coach: " << team.coach << endl; teams.push_back(team); } else { cout << "无效行：" << line << endl; } } }// 按学校查询参赛队伍信息 void searchBySchool(vector<Team>& teams) { string school; cout << "请输入要查询的学校名称：" << endl; cin >> school; bool found = false; for (auto& team : teams) { if (team.school == school) { 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 << "无法找到该学校参赛队伍，请检查输入是否正确！" << endl; } }在运行输入的学校无误后显示未查找到该学校的参赛队伍

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。
