No why ? a const argument is just a promise that the called function doesn't change the memory it points to. Same with char pointers: you can give a 'char *' to a function argument that is 'const char *'. But if you try it the other way round, you'll see a warning (giving a 'const char *' to a 'char *' function argument).
