我用的是DEVCPP编译器，实在是找不出该怎么修改了，请帮帮忙，下面是编译器给出的错误提示!
编译器: Default compiler

[解决办法]
没个说明看得好累的，这段程序是要干什么总要说一下吧
[解决办法]
1.error: no matching function for call to `People::People()
你没有提供People类的默认构造函数,还有其它几处也是同样问题.Teacher类TA类也是没有默认构造函数.
2/函数TA::TA(int, char, CDate, char, char, char, Teacher)中num打错了
3.在TA的成员初始化列表中用了Student类,而Student类并不是TA的基类
就这些吧
[解决办法]
程序居然没一行注释,你太NB了

下面这个可以运行:
class CDate
{
public:
CDate(){setDate();}
void setDate();
void display();
~CDate(){}
private:
int day;
int month;
int year;
};
void CDate::setDate()
{
cout < < "Please input day month and year: ";
cin > > day > > month > > year;
}
void CDate::display()
{
cout < < "The date is: " < < day < < '/ ' < < month < < '/ ' < < year < <endl;
}
class People
{
public:
People(){setData();}//看你main中的调用 ,应该是所有的数据都从键盘输入,所以需要这个无参构造,而后面的有参构造倒反而是可以不要的
//People(int number, char sex, CDate birthday, char *id)//使用函数的人可能不是类的设计都,所以,尽量让函数的参数名易懂.而成员变量反而可以次要点
//{_number = number; _sex = sex; _birthday = birthday; strcpy(_id, id);}
inline People(People &p);
void setData();
void display();
~People(){}
