有如下程序：

#include＜iostream＞

using namespace std;

class Animal{

public:

virtual char*getType( )const{ return "Animal";}

virtual char*getVoice( )const{ return "Voice";)

};

class Dog: public Animal{

public:

char*getType( )const{return "Dog";)

char*getVoice( )const{return "Woof";}

};

void type(Animal& a){ cout＜＜a.getType( );}

void sDeak(Animal a){ cout＜＜a.getVoice( );}

int main( ){

Dog d;type(d);cout＜＜"speak";speak(d);cout＜＜endl;

return 0;

}

运行时的输出结果是______。
