为什么不兼容

class ccc
{
public:
ccc();
void setname(cbv &emp);
private:
cbv *emp[10];
};
ccc::ccc()
{
for(int i=0;i<10;i++)
{
emp[i]=new ccc();
}
}
void ccc::setname(cbv &emp)
{
string strname;
cout<<"321:"<<endl;
cin>>strname;
emp.strname=strname;
};
class cbv
{
public:
friend void ccc::setname(cbv &emp);
string getname(){return strname;}
private:
string strname;
};

求指教
