#include <iostream.h>
#include <string.h>
class NAME{
public:
NAME()
{
cout<<"Constructing."<<endl;
string = NULL;
return;
}
~NAME()
{
cout<<"Destructing"<<endl;
if(string!= NULL)
delete string;
return;
}
void show()
{
cout<<string<<endl;
return;
}
void set(char* s)
{
string = new char[strlen(s)+1];
strcpy(string,s);
return;
}
private:
char *string;
};
NAME get_name()
{
NAME temp_obj;
char temp_str[250];
cout<<"Input your name"<<endl;
cin>>temp_str;
temp_obj.set(temp_str);
return temp_obj;
}

int main()
{
NAME myname;
myname = get_name();
myname.show();
return 0;
}


不知道这个程序那里出错了，请问各位大虾
