/*
As for this declaration

char *n = "hii";
then the string literal "hii" has the type char[4] and internally is represented 
like { 'h', 'i', 'i', '\0' }. Array designators used in expressions with rare 
exceptions are converted to pointers to their first elements.
So the above declaration is equivalent to the following

char *n = &"hii"[0];
