  2. {X = 0, Y = 100} {X = 0, Y = 0} {X = -100, Y = 0} {X = 100, Y = 0} {X = 0, Y = -100}

  3. References to the graphical library

  4. Declaration of a shape object with an initial value

  5. Parameter value given by name

  6. X is a float, so it needs a floating point literal (0.0) not integer (0)
