What is the primary purpose of the __P() macro? Choice 1 The __P() macro has no function, and merely obfuscates library function declarat ions. It should be removed from further releases of the C library. Choice 2 The __P() macro provides forward compatibility for C++ compilers, which do not r ecognize Standard C prototypes. Choice 3 Identifiers that begin with two underscores are reserved for C library implement ations. It is impossible to determine the purpose of the macro from the context given. Choice 4 The __P() macro provides backward compatibility for K&R C compilers, which do no t recognize Standard C prototypes. Choice 5 The __P() macro serves primarily to differentiate library functions from applica tion-specific functions. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - /*question number 68*/ Which one of the following is NOT a valid identifier?
