LANG.STRUCT.SW.SWNEE

Switch with non-enum expression

Could detect violations of this recommendation merely by searching for the use of "magic numbers" and magic strings in the code itself. That is, any number (except a few canonical numbers: −1, 0, 1, 2) that appears in the code anywhere besides where assigned to a variable is a magic number and should instead be assigned to a const integer, enum, or macro. Likewise, any string literal (except "" and individual characters) that appears in the code anywhere besides where assigned to a char* or char[] is a magic string
