Why don’t languages use explicit fall-through on switch statements?
I was reading Why do we have to use break in switch?, and it led me to wonder why implicit fall-through is allowed in some languages (such as PHP and JavaScript), while there is no support (AFAIK) for explicit fall-through.
If-Else V.S. Switch end of flow
I was wondering the if if-else statements, is like a switch statement that does have a break statement.
Why does Clang/LLVM warn me about using default in a switch statement where all enumerated cases are covered?
Consider the following enum and switch statement:
Is it necessary to add the default case while using switch cases?
During a recent code review I was asked to put default cases in all the files wherever switch block is used, even if there is nothing to do in default. That means I have to put the default case and write nothing in it.
Is it possible to avoid enormously big switch in that case? [duplicate]
This question already has answers here: Refactoring Switch Statements and is there any real use for Switch Statements at all? (7 answers) Closed 11 years ago. I’m writing a simple chess-related code with intention to write it clearly (performance doesn’t matter at all). And this method I have doesn’t look clean to me at all: […]

Checking “instanceof” rather than value using a switch statement
Is there some syntax (other than a series of if statements) that allows for the use of a switch statement in Java to check if an object is an instanceof a class? I.e., something like this:
Map of functions vs switch statement
I’m working on a project that processes requests, and there are two components to the request: the command and the parameters. The handler for each command is very simple (< 10 lines, often < 5). There are at least 20 commands, and likely will have more than 50.
Break on default case in switch
I am a bit puzzled on whenever or not to include break after the last case, often default.
