c - #define a string literal then assign it to a char* -

#define maxstr "maximum number reached"  char *str = maxstr; 

while doing kind of operation. code working & running fine getting lint error. how can resolve it?

error: assignment of string literal variable  

if use:

 #define maxstr "maximum number reached"   char *str = (char *) maxstr; 

then lint error:

attempt cast away const (or volatile) 

assignment of string literal variable

that horrible error message. i'm curious lint thinks string literals for, if cannot assign them variables... should like: "assigning string literal non-constant pointer".

attempt cast away const (or volatile)

the warning incorrect. again, should tell pointer variable needs const.

to sum up, errors because static analyser tool bad.

explanation:

string literals in c character arrays, char []. unfortunately not treated constant type const char[] language. defect in c language, because if attempt write access of string literal, leads undefined behaviour , program might crash , burn. must treat string literals if const arrays, though not.

therefore, practice declare pointers string literals const char*.

in case of lint, seems treat string literals if const char[], not. therefore gives incorrect errors instead of pointing out actual problem.
