若有以下程序：
#include ＜iostream＞
using namespace std;
class Base
{
public:
void who()
{
cout＜＜"class Base"＜＜end1;
}
};
class Derivedl : public Base
{
public:
void who()
{
cout＜＜"class Derivedl"＜＜end1;
}
};
class Derived2 : public Base
{
public:
void who()
{
cout＜＜"class Derived2"＜＜end1;
}
};
int main()
{
Base *p;
Derivedl obj1;
Derived2 obi2;
p=&obj 1;
p=&obj2;
p-＞who ( );
return 0;
}
则该程序运行后的输出结果是 【14】 。
【参考答案】
class Derived2
