Here, we can observe there is no comma operator ( (*ptr) , [10]) so, we can identify what's the array name, because the array name must be declared. So, *ptr=a, then the array becomes a[10], 10 elements are there in the array "a".

int ptr[10] means ptr is an array of 10 elements whose datatype is int.
int a;
int *ptr=a; means ptr is a pointer pointing to a which is an integer type.
(int *) ptr[10] means ptr is an array of 10 elements whose datatype is int and they all are pointers.
in (*ptr)[10] means ptr is a pointer which is pointing to 10 elements which are of int datatype.
int a;
int *ptr=a; means ptr is a pointer pointing to a which is an integer type.
(int *) ptr[10] means ptr is an array of 10 elements whose datatype is int and they all are pointers.
in (*ptr)[10] means ptr is a pointer which is pointing to 10 elements which are of int datatype.

As we write ' int a[10] ' then we call it:- a is an array of 10 integer type elements.
Like that we can say in " int (*ptr)[10] "ptr (due to * ptr is pointer variable) is a pointer to an array of 10 integer type elements.
Like that we can say in " int (*ptr)[10] "ptr (due to * ptr is pointer variable) is a pointer to an array of 10 integer type elements.
