• 1

• 2

• 3

Answer explanation

1. Off by one when generating shape length from 1 to maxSize inclusive

2. New length only randomly generated once outside the for loop

The following code for "Option 4: Draw Roadmap" would receive an S...why?

• Random bound for shape sides is off

• Random bound for turn angle is off

• Unused parameters

• Draw too many destinations/shapes

Answer explanation

1. The random shape must have at least 3 sides

2. With fenceposting, their loop should run (numDestinations - 1) times

*we recommend turn angle to be between 20 and 120 degrees, but student can generate any angle
