bool FBullCowGame::IsLowerCase(FString Word) const
{
    for (auto Letter : Word) {
        if (Letter < 'a' || Letter > 'z') { return false; }

Nice and clean Stephen

• My IsLowercase() helper method
  

---

• My IsEmpty() helper method to handle zero length, \0 and spaces
  

• Instead of Word == “” --> Word.length == 0 should be possible, too.
• I don’t know if it would be enough to read the first space, but I search for at least one char in the word.

---

My CheckGuessValidi() method

• I added in the enum class Empty_String
• I changed the check order because I don’t have to look for isograms if the Guess is empty or has uppercases.

---

• In the output I declare the same string for Wrong_Length and Empty_String
  
  

---

• And here my program in action
