;Task:
|
|
::* Create a function (or subroutine) that uses turtle graphics to draw a house of a specified size as depicted. Optionally make it lovely by adding details such as, for example, doors and windows.
|
|
|
|
::* Create a function (or subroutine) that takes a list (array, vector) of non-negative numbers and draws a bar chart from them, scaled to fit exactly in a square of a specified size. The enclosing square need not be drawn.
|
|
|
|
::* Both functions should return the turtle to the location it was at and facing in the same direction as it was immediately before the function was executed.
