Correct Answer (Detailed Explanation is Below)
C.
30
Detailed Explanation
Correct Answer: 30
The array a contains 10, 20, 30 and 40. When p = a, the pointer points to the first element of the array.
p + 2 points to the third element because array indexing starts from 0. Therefore, *(p + 2) gives the value of the third element, which is 30.
So the output is 30.
Important: In C, a[i] is equivalent to *(a+i).
