What section/general location is it in?
Forking -> Process Contents -> Memory Layout -> A Text Segment

The text reads as: "It is important to note that this is the only executable section of the program, by default. If a program’s code while it’s running, the program most likely will SEGFAULT". I'm not quite sure what this second sentence is trying to say

What should it look like?
I think this should say that if the code is modified while running, then the program will SEGFAULT
