// Required for UnrealEngine-friendly syntax:
using FText = std::string;
using int32 = int;

// Function prototypes, as outside class:
FText GetValidGuess();
void MasterControlProgram();
void PrintTurnSummary(FBullCowCounts BullCowCounts, FString& Guess);

// Instantiate a new game named BCGame, which is recycled through each turn and round (or phase):
FBullCowGame BCGame;

// The entry-point for the applciation:
int main()
{
		do { MasterControlProgram(); } while (bAskToPlayAgain());
	return 0;
}

// Core game I/O handler method:
void MasterControlProgram()
{
	BCGame.Reset();
	PrintRoundIntro();
	while (!BCGame.IsPhaseWon() && BCGame.GetTurn() <= BCGame.GetMaxTries())
	{
		FText Guess = GetValidGuess();

		PrintTurnSummary(BullCowCounts, Guess);
		BCGame.IncrementTry();

// Output - Print game introduction, instruction and status text:
void PrintRoundIntro()

	std::cout << "\nThis round you'll need to earn " << BCGame.GetIsogram().length() << " Bulls in one guess to win. Good luck!\n\n";
}

// I/O - Get a valid guess from the player, loop until satisfied:

{
	EGuessStatus Status = EGuessStatus::Invalid_Status;
	FText Guess = "";
	do

		// Acquire input:
		std::cout << std::endl << "Please enter a " << BCGame.GetIsogram().length() << " letter guess, #" << BCGame.GetTurn();

		std::getline(std::cin, Guess);

		// Provide helpful feedback if the guess is unexpected:
		Status = BCGame.CheckGuessValidity(Guess);
	  // ...yada yada... basically it loops here until the player input is validated
	  return Guess;
}

// Output - After a guess is validated, print the results: Guess# of #, Bull# Cow#
