我也来个问题？一天拉都没弄出来！！

#include<iostream.h>
 #include<string.h>
 
class StudentID {  
public:  
    StudentID(int id=0) { value=id; cout<<"assigning srudent id"<<"   "<<value<<endl; }  
    ~StudentID() { cout<<"Destructing id"<<"   "<<value<<endl; }  
protected:  
    int value;  
};  
 
class Student {  
           public:  
               Student(char* pName="noName",int ssID=0)  
               {  
                   cout<<"Constructing student"<<"   "<<pName<<endl;
                   strncpy(name,pName,sizeof(name));  
                   name[sizeof(name)-1]='\0';  
                   StudentID id(ssID);
               }
           protected:  
               char name[20]; StudentID id;  
           };  
               
void main() { Student s("Randy",9818); }
 
Kai同学说得对，一个字符用的是单引号。
