有如下程序: include using namespaee std;class Animal{ public: virtual char*g

有如下程序：

include＜iostream＞

using namespaee std；c lass 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( )eonst{return"Woof"；}

}；

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

void speak(Animal A) {eout＜＜a．getVoice( )；}

int main( ){

D．og d；type(D) ；cout＜＜"speak"；speak(D) ；cout< return 0；

}

程序的输出结果是______。
