I forgot to change the directory. Thats why it shows an error on the first 2 lines of my output.
1. Make your script print another line.
Line 8 of the code is my work.
2. Make your script print only one of the lines.
I didn’t show it in my work, if you would like to try it, just simply put an # (Zed calls it octothorpe) in front of every lines but one.
3. Put a # (octothorpe) character at the beginning of a line. What did it do? Try to find out what this character does.
The octothorpe in ruby is used for commenting, this is helpful is explaining codes for later references.
