could you be more specific?

total is an integer that is initialized to 0, and on every loop, if i is less than or equal to n, total's value increases by having the value of i added to it

i's value is also increased by 1 afterwards

so on the first loop you'd get total = 0 + 1 and i = 1 + 1

then on the second loop it'd become total = 1 + 2 and i = 2 + 1

if you've ever heard someone say the sum of x items/numbers, that's basically what total is here

[elfin hemlock]

Why not total = 0 +2?

[gilded arch]

because you incremented it

the variables' values persist through the loop

[elfin hemlock]

So every loop total increases by 1?

[gilded arch]

it increases by i

[elfin hemlock]

Total at first is 0

And then it’s 0 + 1

And why it’s not 0 (because by default is 0)+2 after

[gilded arch]

it's not 0 after, because 0 + 1 is not 0

[elfin hemlock]

Oh yeah sorry

I think I got it now,thank you so much

Sorry if I maybe annoying

[gilded arch]

you're fine

[fresh gorge]

It isn't by default. It is 0 at the start, bc it was initialized with that value^^

[elfin hemlock]

Alright got it

What would be if it wasn’t for total?

[gilded arch]

what would be what?

[elfin hemlock]

If total wasn’t here in this code

[gilded arch]

then you wouldn't have one

and you probably wouldn't print anything at the end

[elfin hemlock]

How the code would change?

[gilded arch]

or you'd print i

[gilded arch]

you'd remove everything relating to total

[elfin hemlock]

Total is the sum

Right

?

[gilded arch]

it acts as a sum, yes

besides that, it's inherently pointless

the code snippet just demonstrates a loop, none of the operations in the loop have any actual purpose beyond being there so you can see them

[elfin hemlock]

Ok
