若有以下程序: include using namespace std; class Base { public:void who(){ cout

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【 】。
