Answer Posted / yathish nm yadav
CHAR * CONST
means we are making the variable of type
char* as constant i.e,
ex:
char * const p;
means pointer variable p is made constant i.e, its lvalue
is been blocked by compiler at compile time.
ex:
char c;
char *const p= &c;
here p contains the adress of c and we cannot make p now to
point to some other variable.
char t;
p=t; //compile time error.
CONST CHAR *
means the variable pointed to by the const char * is made
constant. i,e.
ex:
char c='a';
const char *p=&c;
here c is made constant n its lvalue is being blocked.
now we cannot change the value of c since it is made
constant.
i.e,
*p='b'; // error
