Not in C/C++, at least not directly, because strings aren't considered integral values. https://en.cppreference.com/w/cpp/language/switch "... any expression of integral or enumeration type, or of a class type contextually implicitly convertible to an integral or enumeration type... "

Additional info: Is there a workaround? Yes, such as hashing. https://stackoverflow.com/questions/2111667/compile-time-string-hashing
