    1. const char *a;

2. char* const a;

3. char const *a;

-Differentiate the above declarations.

Answer:

1. 'const' applies to char * rather than 'a' ( pointer to a constant char )

    *a='F'       : illegal

             a="Hi"       : legal

2. 'const' applies to 'a'  rather than to the value of a (constant pointer to char )

    *a='F'       : legal

    a="Hi"       : illegal

3. Same as 1.
