This is one of those really bad decisions by the C++ committee.

String literals are of type const char [], however, for reasons of
wisdom beyond my grasp, the standard allows sting literals (and only
string literals) to be assigned to a "char * ptr" by implicitly const
casting. More than likely, trying to modify the string literal will
cause your program to segv. Go figure.
