Question

Why is the imho missing indentation of the “case” – keywords in a switch statement considered good style?

No indentation of the “case” keyword seems to be the default formatting option in about every IDE:

switch (i){
case 0:
    break;
case 1:
    break;
}

while I find this format more intuitive:

switch (i){
    case 0:
        break;
    case 1:
        break;
}

Is there some logic behind this, that eludes me?

Answer 1

The cases are logically labels. Many people put labels at the same indentation level as the block they are in. In my opinion, that way it’s easier to read through the text.

I compare it with a timeline you can scroll through. You have markers on the time line itself, not indented into the content. You can then quickly point out where labels/markers are, without moving your eye away from the base-line.
