Hey so you should ignore the value that scanf() reutrns

you are making an if statement with the scanf() inside the if statement

[rigid nebula]

No.

[haughty beacon]

what you should do instead is put the scanf out of it and evaluate the variable that you just read

[haughty beacon]

scanf does not return the number it read

[rigid nebula]

Yes?

[haughty beacon]

it returns the number of characters?

[lost niche]

removed the "if" before the scanf and it made it worse

[haughty beacon]

You should not remove the if

[rigid nebula]

It still returns information if it read something or not. That is important to check^^

[haughty beacon]

you should take the scanf out of the if inside of it

[rigid nebula]

Why?

[haughty beacon]

yes but not for this case

[rigid nebula]

It is.

[haughty beacon]

cuz he wants to evaluate the score of the student

[lost niche]

everything else is correct but it keeps saying this

[haughty beacon]

not the reutnr value of the scanf function

[haughty beacon]

what was the input on that

[rigid nebula]

What if no score was entered

[haughty beacon]

it will read '\n'

it still reads something

[rigid nebula]

No.

[haughty beacon]

hm

the i cant see the error

i rarely use the return value of scanf

[haughty beacon]

what was the input on tose casaes

cases

[lost niche]

wdyn

wdym

[haughty beacon]

it says that the value is not between the range value

limits*

[upbeat rapids]

try removing the 2 printf("Invalid score\n"); lines?

[haughty beacon]

what number did u put to the computer

[bronze geode]

yea

[lost niche]

ok ok

[bronze geode]

scanf doesnt return the number you input it returns how many inputs it took(in this case 1)

[lost niche]

omg thank u

[novel egret]

Why did you add it in the first place?

It's not in the exercise

[novel egret]

So what? Why not check if scanf failed to read the number?

[rigid nebula]

Yes? That was, what i was getting at?

[lost niche]

I thought I needed to make it clearer

[novel egret]

Dude

[bronze geode]

oh my bad i misunderstood then

[haughty beacon]

it is bro

it said that if the value is not between 0 or 100 it should input an error message

[novel egret]

It says to print "Error: score should be in range ..."

[haughty beacon]

am i reading wrong?

[novel egret]

It doesn't say to print "invalid input"

[haughty beacon]

ohhh ok

[novel egret]

The grader is automatic, if you print extra stuff "to make it clearer" of course it's gonna fail you

[lost niche]

i honestly dont even know where to start with the second one

[haughty beacon]

you should learn logic gates

[lost niche]

do I just fine the avg

[bronze geode]

pardon?

[haughty beacon]

it would make you if() alot easier and cleaner

[lost niche]

lemme try brb

[haughty beacon]

Good luck

[bronze geode]

oh so he is checking if theres inputs there with the first if?

[novel egret]

What? 😛

[novel egret]

Yeah

Yeah, you haven't tried much here. Start by calculating the average score

[lost niche]

oh

this is making me lose my mind

[bronze geode]

is declaring grade variables required by the question?

[lost niche]

i think so yes

yeah it is

[bronze geode]

oh ok

[lost niche]

im gonna try to make it calculate the variable brb

avg i mean

[rigid nebula]

That is a fast way for generating bugs and unsafe code^^
No hate, just an advice

[haughty beacon]

Yeah ofc bro im not taking as hate

we're here to help each other

thank you

but like i dont plan on using C as a profession i think

im in 11th grade hs

[rigid nebula]

Idea: recycle the code you used for the first task^^
Maybe encapsulate it in an own function, that just returns the read value, if valid 🙂

[haughty beacon]

Sorry for off topic but how do i delete a repositorie on github

[rigid nebula]

But you can programm robots with it (sorta 😂)

[haughty beacon]

Hhaahha ik for real

[lost niche]

yeah I give up wtf

[haughty beacon]

noo

dont give up bro once you get the hang of it it will be easy

[lost niche]

2 am and i feel sick

[bronze geode]

What's a own function

Recursion?

[lost niche]

do I just calculate the avg using the double avg 😵‍💫

[bronze geode]

Yea I mean why not

[lost niche]

i honestly dont know how

[bronze geode]

Sum of all scores divided by 4

(s1+s2+s3+s4) /4

[lost niche]

so printf("avg score: %d", (score1+score2+score3+score4/4));?

[novel egret]

(s1+s2+s3+s4) /4

score1+score2+score3+score4/4

Do you see the difference?

[bronze geode]

Shoulnt there be parenthesis

[lost niche]

oh yeah my b

it says formatted to two decimals points

omg

[upbeat rapids]

you should use a float or a double as the type of the avg to avoid truncation

[lost niche]

these instructions omfg

[bronze geode]

I think %0.2d then

Try once

[lost niche]

i used double yes

idk how

like %0.2d?

beside like

the /4?

[bronze geode]

Just replace%d with %0.2d

[lost niche]

it made it worse

[bronze geode]

How many decimal points is it showing

[upbeat rapids]

mb didnt notice it

[lost niche]

No

[lost niche]

Like it says everything is mismatched

Idk anymore

[lost niche]

Allng

All g*

[bronze geode]

Could you send a ss of your code

[lost niche]

Omfg my laptop froze

Lemme take a pic

Wait my laptop crashed

Omfg bruh, it’s nearly 3am now

[bronze geode]

damn

you should get some sleep

[lost niche]

I can’t, I have to submit this by tmr

There’s no way it literally erased problem 2

[bronze geode]

are you allowed to use arrays and loops in this program

[lost niche]

I think so

[bronze geode]

then it will be shorter

or else long

[lost niche]

I give up sorry for taking time

I feel too sleepy

[bronze geode]

npnp i couldnt help much either way lol

[novel egret]

Go sleep!

[bronze geode]

ya get some sleep

How do I close btw

[bronze geode]

hey btw i have a question

[autumn moss]

Thank you and let us know if you have any more questions!

This thread is now set to auto-hide after an hour of inactivity

[novel egret]

What is it? 😛

[bronze geode]

why is the data getting rounded off

[novel egret]

int divided by an int always results in another int, truncating the fractional part

It doesn't matter that the result is assigned to a float, the truncation happens before that

You need to make at least one of the operands a float, e.g. / 4.f

[bronze geode]

Ohhh

Thanks ! it worked

[rigid nebula]

No.

int inc(int input);

int main(void) {
    int i = 3;
    i = inc(i);
    return 0;
}

int inc(int input) {
    int output = input + 1;
    return output;
}

inc is a function

main is also a function.

scanf aswell
