    Description

    请定义一个Student类,有4个属性:

    1.char *name:姓名。

    2.int numOfScores:课程数量

    3.int *scores:所有课程的成绩。

    4.int id:学生的编号。

    只有3个方法:

    1. 构造函数

    2.析构函数

    3.void Student::showStudent()方法:用于输出学生的信息。

    请根据样例输出,写出该类的实现。

    Input

    输入分为多行。

    第一行包含3个正整数M,N和P:其中M表明之后输入的测试用例数量;N表示每个人姓名的最大长度;P表示学生学习的课程的数量。

    之后有M行,包含一个学生姓名(没有任何空白符)、P门课程的成绩。

    Output

    见样例。

    注意:所有的输出两两之间用一个空格隔开,且每行输出的首尾都没有空格。

    Sample Input

    3 10 5 Tom 60 61 72 56 89 Jack 99 100 98 89 77 Mary 88 88 88 88 88

    Sample Output

    A student whose name is "Tom" and id is 1 is created! This student is "Tom" whose id is 1. This student's scores are: 60 61 72 56 89 A student whose name is "Tom" and id is 1 is erased! A student whose name is "Jack" and id is 2 is created! This student is "Jack" whose id is 2. This student's scores are: 99 100 98 89 77 A student whose name is "Jack" and id is 2 is erased! A student whose name is "Mary" and id is 3 is created! This student is "Mary" whose id is 3. This student's scores are: 88 88 88 88 88 A student whose name is "Mary" and id is 3 is erased!
