# This is a tricky error. The line number may throw you off.

# 1. What is the name of the file with the error?
# => The error is occuring in the error.rb file.
# 2. What is the line number where the error occurs?

# 4. What additional information does the interpreter provide about this type of error?
# => It lets me know it was expecting the keyword end
# 5. Where is the error in the code?
# => Line 28, where an end needs to be inserted
# 6. Why did the interpreter give you this error?
# => I needed to end both the def and the while

end

# --- REFLECTION -------------------------------------------------------
# Write your reflection below as a comment.
# -The first time I encountered the error relating to a missing "end" was the most difficult for me because I kept scrolling down to the bottom and not understanding why it would tell me the error was on line 170 when there was no code on line 170
# -yes, and the key was acutally reading the error message I was getting in its entirety. Previously I had looked at the line number, looked at my code, and tried to figure out the problem before reading the entire error message. The end error message situation taught me that I should first use the error message code from ruby to understand what ruby thinks the problem is, and then look at my code. 
# -yes
# -described above, google was helpful as well
