在main函数中，需要先创建一个TA对象，然后通过对象调用方法输出TA的信息。

可以按照以下步骤完成：

1. 创建一个TA对象，传入姓名、学号、性别、出生日期、身份证号、职务、所在部门、班级号、研究方向和导师信息。

TA ta("张三", "20210001", "男", Date(2000, 1, 1), "1234567890123456", "助教", "计算机科学与技术系", "计算机1901", "机器学习", teacher("李四", "副主任"));

2. 输出TA的信息，调用对象的方法即可。

cout << "TA name: " << ta.getName() << endl;
cout << "No.: " << ta.getNumber() << endl;
cout << "Department: " << ta.getDpm() << endl;
cout << "Class No.: " << ta.getClassNO() << endl;
cout << "Subject: " << ta.getSubject() << endl;
cout << "Advisor: " << ta.getAdviser().getName() << endl;
