hello I can’t find the error in my code to pass the first test in Queen Attack can you help me find the error: track_c

true ember Oct 24, 2025, 4:46 PM

#

Hello 👋
If you post the code, you already wrote, in a code block it is much, much easier to read 😉
FYI: Code blocks are 3x backticks before and after the code

eager flare Oct 24, 2025, 4:52 PM

#

what??😭

true ember Oct 24, 2025, 4:53 PM

#

If you have code you can paste it like this

int a = 5

by wrapping the text in 3x backticks (one set of 3 before and one set of 3 after the text)

eager flare Oct 24, 2025, 4:54 PM

#

I do not see the contribution with the error of my code 😅

Increase your chance of getting help and look like a pro by sharing codeblocks not images. For example, you can type the following. Note, the ``` must be on their own line.
```
for number in range(10):
total += number;
```
Discord will render that as so:

for number in range(10):
    total += number;

There are people here using screen readers who cannot view images

true ember Oct 24, 2025, 4:55 PM

#

See if you post the code just as a screenshot I'd have to make a ton of assumptions what your code does. Like which values the constants have and such. If you paste the entire code it is much easier to find out what went wrong 🙂

tranquil cosmos Oct 24, 2025, 4:55 PM

#

It's also pretty hard to copy/paste your code to test it out when it's an image 😉 Code is text. Share text as text

#

And, preferably, the whole file

attack_status_t can_attack(position_t queen_1, position_t queen_2) {
    if (queen_1.row > 7 || queen_1.column > 7 || queen_2.row > 7 || queen_2.column > 7) {
        return INVALID_POSITION;
    }

    int diff_row = (int)queen_1.row - (int)queen_2.row;
    int diff_column = (int)queen_1.column - (int)queen_2.column;

    if (diff_row < 0) diff_row = -diff_row;
    if (diff_column < 0) diff_column = -diff_column;

    if (queen_1.row == queen_2.row || queen_1.column == queen_2.column || diff_row == diff_column) {
        return CAN_ATTACK;
    } else {
        return CAN_NOT_ATTACK;
    }
} ```

If you apply the formating via code blocks the discord formating of || won't make spoilers 🙂

tranquil cosmos Oct 24, 2025, 4:58 PM

#

Can you edit your last post and put a ``` before and after your code, @eager flare ?

eager flare Oct 24, 2025, 4:58 PM

#

like that*

tranquil cosmos Oct 24, 2025, 4:58 PM

#

Yes! Thank you. Could you also share the header file?

#

The code references values not defined in the file 🙂

eager flare Oct 24, 2025, 4:59 PM

#

#define QUEEN_ATTACK_H

#include <stdint.h>

typedef enum { CAN_NOT_ATTACK, CAN_ATTACK, INVALID_POSITION } attack_status_t;

typedef struct {
   uint8_t row;
   uint8_t column;
} position_t;

attack_status_t can_attack(position_t queen_1, position_t queen_2);

#endif

tranquil cosmos Oct 24, 2025, 5:00 PM

#

Awesome. How about the failing test details, also in a codeblock?

eager flare Oct 24, 2025, 5:01 PM

#

test 1:Test Failure

Expected 2 Was 1

Your Output

./

tranquil cosmos Oct 24, 2025, 5:01 PM

#

Cool. Do you understand that Expected line?

eager flare Oct 24, 2025, 5:03 PM

#

he wants CAN_ATTACK to return 2 while the one returns 1

tranquil cosmos Oct 24, 2025, 5:04 PM

#

can_attack, not CAN_ATTACK.

#

Do you know what 1 and 2 represent?

eager flare Oct 24, 2025, 5:06 PM

#

this corresponds to the value in my enum attack_status_t

tranquil cosmos Oct 24, 2025, 5:06 PM

#

Right

#

So ... do you understand what's wrong here?

#

The test name has a hint as to what is being tested

eager flare Oct 24, 2025, 5:08 PM

#

yes it sent CAN_NOT_ATTACK back instead ofCAN_ATTACK

tranquil cosmos Oct 24, 2025, 5:08 PM

#

What's 1 and 2 in the enum?

modern bramble Oct 24, 2025, 5:11 PM

#

Apart from what Isaac is saying, another hint is to look at the name of the failing test. It usually specifies what is being tested.

#

ow, Isaac already said that 🙂

tranquil cosmos Oct 24, 2025, 5:17 PM

#

@eager flare ?

eager flare Oct 24, 2025, 5:18 PM

#

yes but I really don’t see the mistake

tranquil cosmos Oct 24, 2025, 5:18 PM

#

What's 1 and 2 in the enum?

eager flare Oct 24, 2025, 5:20 PM

#

CAN_NOT_ATTACK, CAN_ATTACK

tranquil cosmos Oct 24, 2025, 5:20 PM

#

I don't think that's correct

#

What's the integer value that enums start at?

eager flare Oct 24, 2025, 5:37 PM

#

0

#

0 is:I don't think that's correct 1:CAN_ATTACK and 2:INVALID_POSITION

tranquil cosmos Oct 24, 2025, 5:44 PM

#

That sounds more correct

#

So what is the test expecting and what is your code returning?

eager flare Oct 24, 2025, 5:46 PM

#

I have to get back :iNVALID_POSITION and my code return :CAN_ATTACK

tranquil cosmos Oct 24, 2025, 6:02 PM

#

Right. Did you see the test name? Do you understand what case is being tested and why it is invalid?

eager flare Oct 24, 2025, 6:06 PM

#

Yess I understand

tranquil cosmos Oct 24, 2025, 6:07 PM

#

👍

#

Then do you know how to fix that issue?

eager flare Oct 24, 2025, 6:32 PM

#

No 🦧🦧

tranquil cosmos Oct 24, 2025, 6:36 PM

#

I have to get back :iNVALID_POSITION and my code return :CAN_ATTACK

Do you understand what is being tested?
Do you understand why iNVALID_POSITION is the expected value?
Do you understand why your code returns CAN_ATTACK?

eager flare Oct 24, 2025, 7:31 PM

#

I know why but I don't see the error in my code

modern bramble Oct 24, 2025, 7:33 PM

#

The name of the failing test is "invalid_if_on_same_position"

tranquil cosmos Oct 24, 2025, 7:42 PM

#

eager flare I know why but I don't see the error in my code

You understand all three of those?

#

Why do the tests expect invalid? Why doesn't the code return invalid? Can you fix that?

eager flare Oct 25, 2025, 10:16 AM

#

I understood what was asked of me, but I don't see where the mistake is.
