*const char* a* is *equivalent* to *char const * a*
A simple method which most people use in coding is that const is written
after the value which needs to be constant.
So,
*char const *a* means a is a pointer that points to a character which is a
constant i.e you can not change the value which a
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
