Using Spiral-Anderson rule,
1:- const char * a -> a is a pointer to char const (character which is
constant , the value pointed by the pointer is constant)
2:- char * const a -> a is a const pointer to char (pointer is constant, it
always point to same memory location)
3:- char const * a -> a is a pointer to const char (again character is
constant , the value pointed by the pointer is constant)
*a='F'
a ="Hi"
>From above
1 2 3
*a= 'F' Legal Illegal Legal
a="Hi" Illegal Legal Illegal
