Design Process — Part 3
Define, prototype, test, iterate. This is part 3 of 20.
What you'll learn
You will learn the design process: plan it, build a simple version, test it, then improve.
Steps
- 1Good design starts with a plan. The problem here is simple: show a personalized greeting. The solution: store a name, then print it.
- 2This is a 'simple version' — it works! It solves the problem in the fewest lines possible.
- 3Once the simple version works, you can improve it: add more messages, ask for the user's name, add colors.
- 4Real programmers always start simple, test it, then improve. Never try to build everything at once!
Key Terms
- Design
- Planning what the program should do before writing code.
- Simple version
- A first version that does the main thing correctly. Improve it later.
- Improve
- Making the program better after the first version works.
