Quiz Game in C++

In this article, the task is to create a quiz game where the user will be asked questions and the result of each question whether it is correct or wrong with the updated score will be shown.

Below is the implementation of the same:

C++

// C++ program for the above approach
#include <iostream>
#include <string>
using namespace std;

int Guess;
int Total;

// Question Class
class Question {
private:
    string Question_Text;
    string Answer_1;
    string Answer_2;
    string Answer_3;
    string Answer_4;
    int Correct_Answer;
    int Question_Score;

public:
    // Setter Function
    void setValues(string, string,
                   string, string,
                   string, int, int);

    // Function to ask questions
    void askQuestion();
};

// Driver code
int main()
{
    cout << "\n\n\t\t\t\tTHE DAILY QUIZ"
         << endl;
    cout << "\nPress Enter to start "
         << "the quiz... " << endl;

    // Input
    cin.get();

    string Name;
    int Age;

    // Input the details
    cout << "What is your name?"
         << endl;
    cin >> Name;
    cout << endl;

    cout << "How old are you?"
         << endl;
    cin >> Age;
    cout << endl;

    string Respond;
    cout << "Are you ready to take"
         << " the quiz " << Name
         << "? yes/no" << endl;
    cin >> Respond;

    if (Respond == "yes") {
        cout << endl;
        cout << "Good Luck!" << endl;
    }
    else {
        cout << "Okay Good Bye!" << endl;
        return 0;
    }
