23:类的继承——定义点类及其派生的圆类

Time/Memory Limit:1000 MS/32768 K

Submitted: 64 Accepted: 51

Problem Description

定义一个点类point，它带有两个私有数据成员：x,y(整数)；还有构造函数（x和y的默认值为0），显示坐标函数；point类共有派生出圆类circle，circle类具备point类的全部特征，同时自身也有自己的特点：圆有半径成员（可以是小数），求面积成员函数，显示成员函数，该显示函数可以显示圆的圆心坐标，半径，和圆的面积。在主函数中对circle类进行测试。

Input

输入数据有多行，第一行有一个整数n，表示一共有n个圆对象，接下来的n行，每行包括一共圆对象的圆心坐标和它的半径。

Output

输出有n行，每行为一个圆对象的圆心坐标、半径和它的面积。

Problem Description

编写一个学生和教师数据输入和显示程序，学生数据有编号、姓名、班号和成绩，教师数据有编号、姓名、职称和部门。要求设计一个Person类，包含编号、姓名数据成员及构造和显示成员函数，该类作为学生类和教师类的基类。

Input

输入包括两行，第一行是学生的相关信息，第二行是教师的相关信息

Output

输出包括两行，第一行是学生的相关信息，第二行是教师的相关信息
