c++学生信息管理系统的累层次结构图

根据提供的引用内容，可以得出C++学生信息管理系统的类层次结构图如下：

+--+
|     Management    |
+--+
| - students: vector<Student> |
+--+
| + addStudent(student: Student): void |
| + deleteStudent(student: Student): void |
| + modifyStudent(student: Student): void |
| + sortStudentsByScore(): void |
| + saveToFile(filename: string): void |
| + loadFromFile(filename: string): void |
+--+

        |
        |
        V

+--+
|      Student      |
+--+
| - name: string    |
| - studentID: string |
| - scores: vector<int> |
+--+
| + getName(): string |
| + getStudentID(): string |
| + getScores(): vector<int> |
| + setName(name: string): void |
| + setStudentID(studentID: string): void |
| + setScores(scores: vector<int>): void |
