This is a test of your understanding of order of operations. At std::cout you should see that i == 3. What is a[ 3 + a[3]] + a[3]?

i evaluated like a[1+a[2]]+a[3]; tell me the logic of 3 at all places

++i is evaluated first, so the function is: a[ 3 + a[3]] + a[3] not a[1+a[2]]+a[3] thus a[ 3 + a[3]] + a[3] == a[3 +3] + 3 == a[6] + 3 == 6 + 3 == 9
