有如下的程序: include using namespace std; class AT{friend ostream operato 有如下的程序:include<iostream>using namespace std;class AT{friend ostream operator<<(ostream,AT);}at;ostream operator<<(ostream os,AT){return os<<'@';}int main(){cout<<"MyHome"<<at<<"isHere.com";}执行上面的程序将输出
有如下的程序: include using namespace std; class AT{friend ostream & operato
有如下的程序:
include<iostream>
using namespace std;
class AT{
friend ostream & operator<<(ostream&,AT);
}at;
ostream& operator<<(ostream& os,AT){return os<<'@';}
int main(){
cout<<"MyHome"<<at<<"isHere.com";
}
执行上面的程序将输出
