Question

请各位C++高手帮我看一下这简单的C++程序

请帮我改正错误!并稍做解析.谢谢了.以下是程序代码.
/*2、编写一个学生和教师数据输入和显示程序，学生数据要求有编号、姓名、班号和成绩，
教师数据有编号、姓名、职称和部门。要求将编号、姓名的输入和显示设计成一个类person，
并作为学生数据操作类student和教师数据操作类teacher的基类，
学生数据中的班号和成绩的输入和显示在student类中实现，
教师数据中的职称和部门的输入和显示在teacher类中实现。
最后在主函数中进行该类的测试。
下面给出了基类person的主要成员：
（1） 私有成员：
l int no；编号
l char name[10]; 姓名
（2） 公有成员：
l void input(); 编号和姓名的输入
l void display(); 编号和姓名的显示*/

帮你修改正确了，有几个变量你把字母打错了，最主要的错误是你没有理解继承，既然是继承，teacher和studnet是继承类，所以基类的成员要继承下来，所以你在写构造函数的时候要声明一下，你看我写的就清楚了，还有你应该多用指针，老是用数组多别扭
还有最后你写的两行不是成员函数，我帮你都改了
