Answer c is correct.

No Ankur,the answer is only B coz when we declare
int *p;
then it means u declare p is a pointer to integer n when u declare
int ptr[30];
ptr is an array name to integer n here..
int *ptr[30];
ptr is a array of 30 pointers to integers.
int *p;
then it means u declare p is a pointer to integer n when u declare
int ptr[30];
ptr is an array name to integer n here..
int *ptr[30];
ptr is a array of 30 pointers to integers.

int *ptr[30];
it is an array of size 30 that contain integer pointer i.e.
array of 30 pointers to intger.

Yes.int *p;
then it means u declare p is a pointer to integer n when u declare
int ptr[30];
ptr is an array name to integer n here..
int *ptr[30];

[B]. ptr is a array of 30 pointers to integers.
[C]. ptr is a array of 30 integer pointers.
B and C are correct. pointers to integers and integer pointers are the same. For those brand new to coding and with weak english skills , this will be really confusing!

A should be the answer. Because ptr is a pointer to an array of three integer to pointer.

B and C both are same I guess. Integer pointer and pointer to integer means same. Somebody please confirm.

Let p is a pointer.
Declaration:
int a;
int *p=&a;//i.e p points to the content present in address of a...
So in the similar manner,*p[2] points to the address of some to variables say a ,b..
In the similar manner *p[30] points to 30 integer variables.

In declaration:
int p[20][30]; -> 20 elements each of which is an array of 30 ints.
is equivalent to int *p[30];
So, p is a pointer to an array of 30 ints.
int p[20][30]; -> 20 elements each of which is an array of 30 ints.
is equivalent to int *p[30];
So, p is a pointer to an array of 30 ints.
