Output question in for loop i+=2...

Question

Hey again. I know this should be simple but when I run through the loop I end up with a total number of 8 instead of 9. Why?

Answer 1

why do you think i stops at 6?

why don’t you try printing i in the loop and see what’s going on

Answer 2

Since there is an increment operation on i (i.e, i++) it initially holds 7. And then i+2 is 9

Answer 3

But if I do this: for (i = 0; i<=6; i++){

cout << i;

Then it runs until 6, so 0123456... I guess I get confused with the 0, which means the loop runs 7 instead of 6 times, yes? :)

Answer 4

Thanks again for your answers!!
