 Overclass (int a, int b){x = a; y = b;}
};

int main (){
 Overclass A; 
 Overclass A1(5);
 Overclass A2(96, 28);
 cout<<"Overclass  A's x, y value:: " <<A.x<<", "<<A.y<<"\n";
 cout<<"Overclass  A1's x, y value:: " <<A1.x<<", "<<A1.y<<"\n";
 cout<<"Overclass  A2's x, y value:: " <<A2.x<<", "<<A2.y<<"\n";
 return 0;
}

Overclass  A's x, y value:: 0, 0
Overclass  A1's x, y value:: 5, 5
