#Why is the sum of the numbers up to the number we entered as the output?

hm
yeah, what @fallen cliff said
also, don't do printf("Enter a number: ", N), that N is irrelevant and at best won't do anything
(at worst, it could screw with the stack itself; but virtually every compiler will pass it as a register argument so it wont; but it's possible)
quiet quest
also you should initialize `i` to 0
yeah but S+=i, that means 0+1=1 so ,=1
quiet quest
I didn't understand anything :/
fallen cliff
i <= N
hasty tangle
yeah but S+=i, that means 0+1=1 so ,=1
not necessarily
i doens't start at 0, it starts at an undefined number
since you didnt initialize it, it doesnt start with any particular value

Might be wrong, but I am thinking the OP thinks that
int N, i, S = 0;
Initialises all those variables.
quiet quest
if we said that N is 2 at first , 0 <= 2 it will work then S is 0 at first and S+=i so S has a new variable which is 1 and in this case i will be 1. After that, there is i++, then the new variable of i is gonna be 2. Am I wrong?
and so on
hasty tangle
Might be wrong, but I am thinking the OP thinks that
```c
int N, i, S = 0;
```
I...
C strikes once again
velvet shell
@quiet quest
Try
int N, i = 0, S = 0;
why
hasty tangle
because C's syntax is not terrific
int N, i, S = 0 is the same as ```c
int N;
int i;
int S = 0;
what is the difference from that, int N, i , S = 0;
hasty tangle
because int N, i = 0, s = 0 initializes i too
quiet quest
`int N, i, S = 0` is the same as ```c
int N;
int i;
int S = 0;
```
in this case, we don't know the variables of N and i. Why the outputs work
hasty tangle
it doens't
the compiler can do whatever it want, and what it's doing is not what you expect, hence the error
quiet quest
interesting
it is very interesting that there is a rule when the compiler did what ever it wants
quiet quest
also, don't do `printf("Enter a number: ", N)`, that `N` is irrelevant and at be...
what should I do then in this case
hasty tangle
just omit , N
quiet quest
just omit `, N`
it doesn't necessary because we already used scanf, right?
hasty tangle
correct, i think you were just confused there
hasty tangle
still it gives us 3 when we say that N is 2
probably need to start i at 1
velvet shell
or:
while (i < N)
either or i think
this is where it becomes math and not c errors, and im not great at math lol
velvet shell
Let N = 3
i will then increment through [0, 1, 2]
quiet quest
correct, i think you were just confused there
yeah
hasty tangle
you had the right idea
it's just C being a what, 50, 60 year old langauge? fucked you pu
quiet quest
😂
quiet quest
Let `N = 3`
`i` will then increment through [0, 1, 2]
what about S 😄
velvet shell
what about S 😄
I cannot currently answer that question, but counter it with another.
With N = 3, what do you expect S to be in the end?
quiet quest
3+2+1+0= 6
velvet shell
I mean, you said
if we enter 2 as a new variable of N, S should be 2 I think
I am not sure how you arrive at 2.
It would either be 0 + 1 = 1 or 1 + 2 = 3.
velvet shell
You need to tell us what the algorithm is.
We've seen the code, but we have no way of knowing if the code fulfills the requirements of your assignment.
quiet quest
it comes from my teacher's slide
it's just an example
damn
I forgot to write somethings
I'm a fool person sorry guys
but still it had to work 😄
hasty tangle
the fact that they put spaces after the function hurts
velvet shell
"until N"
Possibly me, but I find constructs like these ambiguous.
The code is not however.
