Unclear line reference

[logananglin98]

Is your feature request related to a problem? Please describe.
In section 3.5, the last paragraph refers to code on "line 8". The code it is referring to appears to be on line 7. There is also another line reference to "line 22" later in the paragraph.

Describe the solution you'd like
Instead of specifying the line the code in question is on, I think it would be better to copy the code in c tags to this part of the paragraph.

Describe alternatives you've considered
We could also just update the text to say "line 7".

either or both would be fine.
