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______。
