解决代码存在的问题：terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc，代码输入到graduate的数据后就终止了，如何解决?求解正确输入输出！！！
people类派生出student类，添加属性：班号string classNO；从people类派生出teacher类，添加属性：职务string principalship、部门string department。从student类中派生出graduate类，添加属性：专业stringr subject、导师teacher advisor；从graduate类和teacher类中派生出TA（助教）类，注意虚基类的使用。用成员函数实现对人员信息的录入和显示。附：people类的属性：number（编号）、sex（性别）、birthday（出生日期）、id（身份证号）等等。其中“出生日期”声明为一个“日期”类内嵌子对象。
