Top-Down Design and Decomposition Quiz

What is the main purpose of top-down design in problem solving?

• To make problems more complicated and detailed

• To break large, complex problems into smaller, manageable parts

• To solve problems from the bottom up using trial and error

• To avoid planning and jump straight into solutions

In the Karel robot hurdle race example, why is it better to create separate functions like `runToHurdle()` and `jumpOverHurdle()` instead of writing all the code in one long sequence?

• It makes the code longer and more impressive

• It makes it easier to test, debug, and understand each part

• Karel robots can only understand short functions

• It uses less computer memory

A programmer is creating a video game where a character must navigate through a maze, collect treasures, and defeat enemies. How should they apply top-down design?

• Write all the code at once without planning

• Focus only on the graphics first

• Create main functions like `navigateMaze()`, `collectTreasures()`, and `fightEnemies()`, then break each into smaller steps

• Copy code from another game exactly

What is a key advantage of using decomposition when working on group projects?

• One person can do all the work while others watch

• Different team members can work on different parts simultaneously

Why might a programmer choose to break down `cleanKitchen()` into smaller steps like `clearCounters()`, `washDishes()`, and `sweepFloor()`?

• To make the program run faster

• To make it easier to modify one part without affecting others

• Because robots can only do one thing at a time

• To impress other programmers with complex code

Which statement best explains why top-down design reduces feeling overwhelmed?

• It makes problems disappear completely

• It allows you to focus on one small, achievable task at a time

• It means you don't have to finish the whole project

• It makes problems seem less important
