可以帮本人看下Menber类那里出现的问题吗？代码运行后显示 已停止工作。

char *sname;
char *ssex;
int sage;
但没有初始化以下成员：
char *gname;
char *gsex;
int gage;
m1.Showme(); 这句函数中将使用了未初始化的变量

顶，你的setname(),setage(),setsex()没用上gname/sex/age没初始化
10
派生类的构造函数的参数不对应。你char*n,member(j就应该是n，而不是gname)

用指针去存储数据， 以后空间很难管理， 原因是不知道是指向常量字符串， 还是 堆内存分配的字符串.
释放堆内存管理也比较麻烦。
class Menber{

strncpy(m_szname,n,sizeof(m_szname)-1) ;
m_chSex = s ;

char m_chSex ;

s1变量中的那几个变量仍然没有初始化
