Your code works well. I'd use isalpha(name[i]) instead of name[i] >= 'A' && name[i] <= 'z', but for the test cases, your code works well.

Maybe you forgot to save the file before compiling, or forgot to make initials before running check50?

  • I don't think its either of those. Just tried your recommendations.Thanks btw Mar 10 '17 at 9:52
  • The "NEY" is not part of the code you shared, that's why I assume you removed it, but forgot to save before submission, or saved in a different directory, or another name. My remark on make initials is completely wrong, as check50 would take the source code, not the compiled file.
