Answer is D.
It is not a pointer to pointer.So we cannot use two stars.
| Is This Answer Correct ? | 6 Yes | 1 No |
The wrong answer is
d> *(*pa+5)
here value pointed to by pa is accessed and added 5 to it
then trying to print the value at that address, which gives
us an warning with some garbage value.

Answer / vignesh1988i
d) is the wrong choice...... because , first variable pa
refers to a address of the array... * of that pa will give
you the first value of the array.. ie a[0] , then that value
will be getting added with 5 and the * which is outside wont
have any value towards this manuplation...... so this will
show an error...... illegal use of pointers.....
thank u
