The study concluded that two-to-four-space indentation was optimal. The second lowest were achieved on programs that used six-space indentation. The lowest comprehension scores were achieved on programs that were not indented at all. The same study found that it was important to neither under-emphasize nor over emphasize a program’s logical structure. Subjects scored 20 to 30 percent higher on a test of comprehension when programs had a two-to-four-spaces indentation scheme than they did when programs had no indentation at all. A blank line (or two) help visually separate out logical blocks of code.įor example, from Steve McConnell's Code Complete, Second Edition chapter on Layout and Style: Whitespace is crucial to clean readable code. So, how do you actually use (or not) blank lines in code ? I consider than the two statements have clear distinct purposes and thus deserve to be separated to make it obvious. I don't consider all this white space a waste because I actually use it to structure the code (as I use the indentation in fact), and therefore I feel it worth the screen estate it takes.įor example: for (int i = 0 i < 10 ++i) in a method, I make one paragraph per step of the processĪll in all, I rarely have more than 4/5 lines clustered together, meaning a very sparse code.if I need to write a comment I'll usually put a blank line before the comment.in a class, I will group methods that go together, while separating them by a blank line from the next group.In fact, I would say I structure my code like I write: I make paragraphs, no longer than a few lines (definitely shorter than 10), and try to make each paragraph self-contained. I myself tend to sprinkle my code with blank lines in an attempt to segregate things that go together in 'logical' groups and hopefully make it easier for the next person to come by to read the code I just produced.

There has been a few remarks about white space already in discussion about curly braces placements. It is not currently accepting new answers or interactions. This question and its answers are locked because the question is off-topic but has historical significance.
