Answer 2

beacuse when i becomes 11 in for loop, k becomes 6+0.5*12=6+6=12
so the next time i (value of i is 12 now) becomes equal to k and the loop won't run. So when you print i you get 12.

Answer 3

where from the 11?

Answer 4

I starts at 0, k starts at 6. In each iteration i is increased by 1 and k by 0.5, so i "catches up" to k. Loop stops when i>=k, so when i caught up to k. That is at i=12
