Answer / susie
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.

Answer / srinivas
The answers for first and third case is fine,but in 2nd
case we cannot assign *a='F',becoz *a points to starting
address of the array you cannot change the value at that
address where the reference to that pointer is lost.
