实现专业类Major,要求数据成员至少包括专业名称string MajorName、专业代码st？
实现专业类Major，要求数据成员至少包括专业名称string MajorName、专业代码string MajorNo；成员函数至少包括ShowMajorName()、ShowMajorNo()、构造函数、复制构造函数、析构函数。基于Major类，实现组合类Student，要求私有数据成员至少包括：姓名string name、 学号string no、年龄int age、专业Major major；成员函数至少包括SetStudent()、ShowStudent()、构造函数、复制构造函数、析构函数。运行出结果并分析构造函数与复制构造函数的调用情况。
