When I search for source-code of Linux parts (applications, kernels, ...), I often find commentaries to clarify the code.
Now, I know that those commentaries are useful to help a human reading the code, but I was wondering about the impact they have on the machine.
The commentaries aren't read by the machine, but I'm assuming the machine must at least read the first character of the line to know if it needs to read it or not :
Machine - "Does this line start with a # ? Yes, OK, moving on ! Uh, another line, does this one start with a # ? No !! AHA, let's read that mo****er !"
So, my question is :
- Do the commentaries in the source-code slow down the machine (in a significant way, like 0,01% or more) ?
PS : maybe the builder which reads the code doesn't include the commentaries in the final program ?
