HI, that's pretty much as my attempt - except I didn't add the trapdoors for overlength guesses :)
/* receives a VALID guess and increments try # and returns count */
FBullCowCount FBullCowGame::SubmitGuess(FString Guess)
{
// increment try
MyCurrentTry++;

// set up return variable
FBullCowCount BullCowCount;

// loop through all the letters in the guess
int32 HiddenWordLength = MyHiddenWord.length();

for (int32 MHWChar = 0; MHWChar < HiddenWordLength; MHWChar++) 
{
	// compare letters against the hidden word
	for (int32 GuessChar = 0; GuessChar < HiddenWordLength; GuessChar++) 
	{
		// if a letter in guess is same as a letter in hidden word
		if (Guess[GuessChar] == MyHiddenWord[MHWChar]) 
		{
			// if the matching letter is in the same position then increment bulls
			if (GuessChar == MHWChar) 
			{ 
				BullCowCount.Bulls++; 
			}
			else // if not then increment cows
			{
				BullCowCount.Cows++;  
			}
		}
		else 
		{
			// ignore it as it doesn't match at all
		}
	}
}
return BullCowCount;
