Final answer:
The value of ia[1] is 2.
Step-by-step explanation:
The given code initializes an integer array ia of size 2, and a pointer variable ip. The pointer ip is then assigned the address of the array ia. The elements of the array ia are then assigned values 1 and 2.
The expression *(ip + 1) = *ip + 1 means that the value at the address (ip + 1) is updated with the value at the address ip plus 1. In this case, the value at the address ip is 1, so the value at the address (ip + 1) becomes 1 + 1 = 2.
Therefore, the value of ia[1] is 2.
