ret... | For the second scenario, if the function is supposed to return something, you don't 'need' the else, but you should at minimum return false. Personally, I don't like putting the else, because it requires the developer to read through more conditions to determine what is returned. Instead, at the bottom, put return true... |

It's also a very common pattern to use, and IMHO, makes code more readable.
For the sake of code clarity/clean coding, if you're returning a boolean you should return a boolean even if the if() doesn't match.

HOWEVER, the real question is if doing so improves readability. This is debatable, and can vary from developer to developer depending on preference and coding standards. |
