Question

Create a Hangman game using C++ by QT creator.

please separate each code that will insert in hider files and cpp files and use an accurate screeshoots if needed.

Thanks in advance.

Answer 1

This is the working code for Hangman game developed by QT creator.

#include "HanGame.h"

#include <QFile>

#include <QDebug>

#include <QBuffer>

#include <QRandomGenerator>

#include <QtConcurrent/QtConcurrentRun>

// Code for HanGame.h header file

HanGame::HanGame(QObject *parent)

    : QObject(parent)

    , m_lock(QMutex::Recursive)

    , m_vowelsUnlocked(false)

{

    connect(this, &HanGame::vowelBought, this, &HanGame::registerLetterBought);

    QtConcurrent::run(this, &HanGame::initWordList);

    m_vowelsUnlocked = m_persistentSettings.value("Hangman/vowelsUnlocked", false).toBool();

    m_vowelsAvailable = m_persistentSettings.value("Hangman/vowelsAvailable", 0).toInt();

    m_wordsGiven = m_persistentSettings.value("Hangman/wordsGiven", 0).toInt();

    m_wordsGuessedCorrectly = m_persistentSettings.value("Hangman/wordsGuessedCorrectly", 0).toInt();

    m_score = m_persistentSettings.value("Hangman/score", 0).toInt();

// Game Reset Code
