那个析构函数不知道应该怎么弄,应该是在定义name,id,department时用 new 的,但是····没成功·····
老师这么写的:
CPerson::CPerson(char *name,char *id,int sex,int age)
{
m_szName=new char[strlen(name)+1]; //此处的处理是个重点,处理不好,会在程序中植入非常严重且隐蔽性极强的“定时炸弹”
strcpy(m_szName,name);
m_szId=new char[strlen(id)+1]; //同上
strcpy(m_szId,id);
m_nSex=sex;
m_nAge=age;
}
CPerson::~CPerson()
{
delete [ ]m_szName;
delete [ ]m_szId;
}
