有以下程序
#include＜iostream＞
#include＜string＞
using namespace std；
class base
private：
charbaseName[10]；
public：
base()
strcpy(baseName,"Base")；
virtual char*myName()
return baseName;
char *className()
return baseName;
;
class Derived: public base
private:
char derivedName[10];
public:
Derived()
strcpy(derivedName,"Derived");
char *myName()
return derivedName;
char *className()
return derivedName;
;
void showPtr(base &p)
cout＜＜p.myName0＜＜" "＜＜p.className();
int main()
base bb;
Derived dd;
showPtr(dD) ;
retum 0;
动行后的输出结果为
A．Derived Base
B．Base Base
C．Derived Derived
D．Base Derived
