Consider an 1-d array of type int and a pointer pointing variable pointing to the 2nd item of the array. Write down the code for the following: int arr(10) = (5,6,23,4,89,70,12,78,33); int *ptr = arr+1; (a) Print the first item of the array using ptr. (b) Print all prime numbers of the array using value at address. (c) Print the last item of the array using a pointer to an array. You are not allowed to initialize the pointer to the address of the last item. Iterate using a loop to change the value of the pointer. (d) Now print the array in reverse order using a pointer. 101

3. Consider an 1-d array of type int and a pointer pointing variable
pointing to the 2nd item of the array. Write down the code for the
following:
int arr(10) = (5,6,23,4,89,70,12,78,33);
int *ptr = arr+1;
(a) Print the first item of the array using ptr.
(b) Print all prime numbers of the array using value at address.
(c) Print the last item of the array using a pointer to an array.
You are not allowed to initialize the pointer to the address of
the last item. Iterate using a loop to change the value of the
pointer.
(d) Now print the array in reverse order using a pointer.
