求教！！！！！(100分)

设计一个多态数组，该数组可以存放学校中的各类人员，如学生，教师，临时工等。
编 写一个程序演示这个多态数组的用法？

看到你的名字里有一个坤，我就来回答你的问题。
Class CSchoolPerson
{
public:
CSchoolPenson(){};
virtual CSchoolPenson(){};
public:
virtual void WhoAmI()
{
printf("i am a schoolperson/n");
}
}
Class CTeacher : public CSchoolPerson
{
public:
CTeacher(){};
virtual CTeacher(){};
public:
virtual void WhoAmI()
{
printf("i am a Teacher/n");
}
}
Class CStudent : public CSchoolPerson
{
public:
CStudent(){};
virtual CStudent(){};
public:
virtual void WhoAmI()
{
printf("i am a Student/n");
}
}
void main()
{
CSchoolTeacher *pteacher = new CTeacher;
CStudent *pstudent = new CStudent;
CArray<CPerson,CPerson*> ob;
ob.add(pteacher);
ob.add(pstudent);
for(int i = 0;
i < ob.GetSize();
i ++)
{
CPerson *pPerson = ob.GetAt(i);

pPerson->WhoAmI();
}
}
大致上是这个样子，我没有用编译器来确定是否通过运行，
只是随便打出来的。

你的程序看上去感觉是用c编写的，因此是不是要进入c++build里编译！

我是随便写的，不用去编译啊，
我只是告诉他堕多态的意思。

提供参考哦！

接受答案了.
