有以下程序
#include ＜iostream＞
#include ＜string＞
using namespace std;
class base
private:
char baseName[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.myName()＜＜" "＜＜p.className();
int main()
base bb;
Derived dd;
showPtr(dd);
return 0;
运行后的输出结果为
A．Derived Base
B．Base Base
C．Derived Derived
D．Base Derived
