IsLowecase() + some other helpful functions! wow

Okay so… first I added some more Error status to handle different scenarios.

// Errors handling
enum class EGuessStatus
{
	Invalid_Status,
	OK,
	Is_Empty,
	Invalid_Character,
	Has_Space_Character,
	Not_Isogram,
	Wrong_Lenght,
	Not_Lowercase
};

Then added them to CheckGuessValidity()…

// Check if the GuessWord is valid and returns various error states
EGuessStatus FBullCowGame::CheckGuessValidity(FString GuessWord) const
{
	if (GuessWord.empty())
	{
		return EGuessStatus::Is_Empty;
	}
	else if (HasSpace(GuessWord))
	{
		return EGuessStatus::Has_Space_Character;
	}
	else if (HasInvalidChar(GuessWord))
	{
		return EGuessStatus::Invalid_Character;
	}
	else if (GetHiddenWordLenght() != GuessWord.length())
	{
		return EGuessStatus::Wrong_Lenght;
	}
	else if (!IsIsogram(GuessWord))
	{
		return EGuessStatus::Not_Isogram;
	}
	else if (!IsLowercase(GuessWord))
	{
		return EGuessStatus::Not_Lowercase;
	}
	else
	{
		return EGuessStatus::OK;
	}
}

and added the needed functions…

private:

    bool IsLowercase(FString) const;
	bool HasSpace(FString) const;
	bool HasInvalidChar(FString) const;

defined and made the logic…
// I found usefull stuff for the string methods here http://en.cppreference.com/w/c/string/byte/isblank

bool FBullCowGame::HasSpace(FString GuessWord) const
{
	for (auto Letter : GuessWord)
	{
		if (isspace(Letter))
		{
			return true;
		}
	}
	return false;
}

bool FBullCowGame::HasInvalidChar(FString GuessWord) const
{
	for (auto Letter : GuessWord)
	{
		if (iscntrl(Letter) || ispunct(Letter) || isdigit(Letter))
		{
			return true;
		}
	}
	return false;
}

bool FBullCowGame::IsLowercase(FString GuessWord) const
{
	for (auto Letter : GuessWord)
	{
		if (!islower(Letter))
		{
			return false;
		}
		else
		{
			return true;
		}
	}
	return true;
}

and finally made the output!

	case EGuessStatus::Not_Lowercase:
		std::cout << "Oops! Your word contains some uppercase letters. Please enter all lowercase letters.\n\n";
		break;
	case EGuessStatus::Is_Empty:
		std::cout << "Oops! You didn't enter a word. Please type some letters.\n\n";
		break;
	case EGuessStatus::Has_Space_Character:
		std::cout << "Oops! You word contains a space. Please type the word again.\n\n";
		break;
	case EGuessStatus::Invalid_Character:
		std::cout << "Oops! You word contains an invalid character. Please type the word again.\n\n";
		break;

…and incredibly everything works!

wow! much code!

Just sharing my happiness :grinning:
