Tests / expectations of the set-up on your machine probably do not not exactly match those of the actual kata here on the site. For example, if you read the error messages, you'll see that your code fails on the first Sample_Test, returning false, and yet it is a pangram.

Hey. So I coded a function for this in C, and when entering the test cases manually in my IDE, I get the correct results. However, I'm told that they're incorrect by the editor (the same goes for the attempt tests). Not sure what to make of this. Help?
