类的继承错误 初学 请多指教
程序代码：//person是student，teacher的基类。而teacher_student又是student和teacher的子类。
//并且继承之间都是pubilc 且无虚继承。
//错误发生在 Teacher_student类的writein_tofile()函数的第三行"out<<name<<" "<<sex<<" "<<age<<" "<<IDstudent<<" "<<IDclass<<" "<<IDteacher<<'\n';"
// error C2385: 对“name”的访问不明确
// 1> 可能是“name”(位于基“Person”中)
// 1> 也可能是“name”(位于基“Person”中)
//error C2385: 对“sex”的访问不明确
// 1> 可能是“sex”(位于基“Person”中)
// 1> 也可能是“sex”(位于基“Person”中)
// error C2385: 对“age”的访问不明确
// 1> 可能是“age”(位于基“Person”中)
// 1> 也可能是“age”(位于基“Person”中)
