c - break in a case with return.. and for default

Question

My OCD makes me add "break" when writing case statements, even if they will not be executed. Consider the following code example:

switch(option) {
    case 1:
        a = 1;
        b = 7;
        break;
    case 2:
        a = 2;
        b = 4;
        return (-1);
        break;
    default:
        a = -1;
        break;
}

My two questions are:
For "case 2:", I don't really need the break, but is it a good idea to have it there anyway? For "default:". Is it purely OCD, or is there any real reason to have the break here?

Answer 1

You don't need either break, but there's no harm in having them. In my opinion, keeping your code structured is worth having a couple of extraneous statements.
