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) {
    cas         


        

Answer 1

Regarding the comment that others have made that they leave the break in the default case in case someone comes by later and adds a case after it: Where I work, the coding standard says to always put the default as the last case; so in our situation, a break on that case is just redundant. (This is one case where I agree wholeheartedly with the company's coding standard, because with the default case always being the last one, you always know where to find it, even in a long switch-statement.)

As for breaks after returns, I tend to omit the break unless there are any execution paths that do not return, as I find it redundant. (My exception to this is, on the rare occasions when there are several execution paths in a case and I can't tell with a quick scan of the code whether or not they all return, then I'll leave the break in just to be safe.)
