Question 6：
Explanation: If the system is 32-bit system, then the size of pointer will be 4 bytes. For such a system, the size of array a will be 4×10 = 40 bytes. The size of pointer is 8 bytes on a 64 bit system. For the given array a of 10 elements, it will be 8×10 = 80 bytes.
Question 7：
Explanation: Array element a[1] is storing an address of character pointer. For a 32-bit systems its 4 bytes and for a 64-bit system, its 8 bytes.
