I have added a little bit more to this exercise. Line 11-15, I’ve added a multi-line comment. This is not recommended? I’m not sure why. In the Common student questions list, Zed didn’t reveal this on purpose.
1. Find out if you were right about what the # character does and make sure you know what it’s called (octothorpe or pound character).
Yes, I’m right, it’s for commenting.
2. Take your ex2.rb file and review each line going backward. Start at the last line, and check each word in reverse against what you should have typed.
I believe he placed a : in line 6 on purpose. In many cases, I would have typed a . instead.
3. Did you find more mistakes? Fix them.
I believe I got it pretty well, although I still haven’t fully adapt to reading backwards.
4. Read what you typed above out loud, including saying each character by its name. Did you find more mistakes? Fix them.
I didn’t do it. But I should. I’m very impatient sometimes, I tend to read things without really reading them.
