Directions: A friend loves red shapes so we’ve decided to write a program that makes it easy to generate them. Write a function called red-shape which takes in the name of a shape and makes a 20-pixel, solid, red image of the shape.
Contract and Purpose Statement |
Every contract has three parts…
red-shape::String->Image
Given a shape name, produce a solid, red, 20-pixel image of the shape.
Examples |
Write some examples, then circle and label what changes…
examples:
__red-shape ("circle")__ is circle(20, "solid", "red")
__red-shape ("triangle")__ is triangle(20, "solid", "red")
__red-shape ("rectangle")__ is rectangle(20, 20, "solid", "red")
__red-shape ("star")__ is star(20, "solid", "red")
end
Definition |
Write the definition, giving variable names to all your input values…
fun _________(_____):
__if _____________________________________________
__else if _________________________________________________
__else if _______________________________________________________
__else if _________________________________________
__else: ______________________________________
__end
end
