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 }>
