下列程序运行结果是 。 class people{ int x , y ; public : people(){ cout ＜＜ "default constructor \n"; x=y=0 ; cout ＜＜ " One \n" ; } people(int i ){ x=i ; y=0 ; cout ＜＜ "constructor \n"; cout ＜＜ " Two \n" ; } ~people() { cout ＜＜ "destructor \n" ; } void print() { cout ＜＜ x ＜＜ setw(5) ＜＜ y ＜＜ endl ; } } ; void main() { people *ptr ; ptr=new people[2] ; ptr[0]=people() ; ptr[1]=people(3) ; for(int i=0 ; i＜2 ; i++) ptr[i].print() delete [ ]ptr }＞
