Given a point with co-ordinates x, y write a function to check if it lies in a box whose center co-ordinates, width and height are known.

class BOX
{
 int center_x;
 int center_y;
 int width;
 int height;

public BOX()
{
   //initialize center width,height
}
boolean IsOnBox(int x,int y);
  {
    return ( (x >= center_x - width/2) && (x <= center_x + width/2) && (y>=center_y-  height/2) && (y <= center_x-height/2) )
  }
}
