What is the difference between char * const and const char *?

Question

What\'s the difference between:

char * const 

and

const char *

Answer 1

1. const char* x Here X is basically a character pointer which is pointing to a constant value

2. char* const x is refer to character pointer which is constant, but the location it is pointing can be change.

3. const char* const x is combination to 1 and 2, means it is a constant character pointer which is pointing to constant value.

4. const *char x will cause a compiler error. it can not be declared.

5. char const * x is equal to point 1.

the rule of thumb is if const is with var name then the pointer will be constant but the pointing location can be changed , else pointer will point to a constant location and pointer can point to another location but the pointing location content can not be change.
