Hey, thanks for the contribution, could you add a couple of example uses of your function ?
Take a look at other snippets...
Also as this doesn't use any C++ feature, i think it belongs to the C language instead.

I also just noticed you added a space before the : of some properties, please remove it as it does not follow our snippet style

Hi @Mathys-Gasnier,

Thank you for your feedback and for taking the time to review my contribution!

Since the function works for both C and C++, I could either update it with examples, depending on what best aligns with the repository’s goals. I’ll also fix the snippet style issues like the spacing before the : in the metadata.

Thank you again for your guidance, and I’ll have the updates ready soon!

Best regards,
Beast177

Hey, Thank you for your contribution.

After reviewing your PR, we notice that it doesn't follow our guidelines.
You can find theses guidelines in CONTRIBUTING.md in the root of the repo.

The odd-even-check.md file doesn't match the scope of Quicksnip, as you mentioned, It's more of a demonstration than an actual useful snippet.
Please remove function from your PR.

If you have any question or would like to contest this decision please leave a comment in your PR explaining your position.

If no fix is provided within 7-10 days this PR will be closed without further notice
