Question

What is the output of this code? int arr[ ] = new int[3]; for (int i = 0; i < 3; i++) { arr[i] = i; } int res = arr[0] + arr[2]; system.out.println(res);?

Answer 1

For loop runs three times as follows
when i = 0, arr[0] = 0
when i = 1, arr[1] = 1
when i = 2, arr[2] = 2

So
res = arr[0] + arr[2] = 0+2 = 2

so the output,
$2$
