Question

I have read that it is best to aim keep functions to no more than approx a screen full of lines.

Is there a similar guideline for module (file) sizes?

I have read several C programming style guidelines but cannot find reference to recommended module sizes (only that of functions)

I apologise if this is akin to asking how long a piece of string is – but I would be very interested in seeing if there is some agreement among experts on this?

Answer 1

I would recommend using a separate .h and .c file for each struct and associated functions, and if possible not have more than a 1000 lines per file.
