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 Classclass 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 codeint 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;    }     // Objects of Question Class    Question q1;    Question q2;    Question q3;    Question q4;    Question q5;    Question q6;    Question q7;    Question q8;    Question q9;    Question q10;     // 3 is the position of    // correct answer    q1.setValues("Question : ", "Answer 1",                 "Answer 2", "Answer 3",                 "Answer 4", 3, 10);    q2.setValues("Question : ", "Answer 1",                 "Answer 2", "Answer 3",                 "Answer 4", 3, 10);    q3.setValues("Question : ", "Answer 1",                 "Answer 2", "Answer 3",                 "Answer 4", 3, 10);    q4.setValues("Question : ", "Answer 1",                 "Answer 2", "Answer 3",                 "Answer 4", 3, 10);    q5.setValues("Question : ", "Answer 1",                 "Answer 2", "Answer 3",                 "Answer 4", 3, 10);    q6.setValues("Question : ", "Answer 1",                 "Answer 2", "Answer 3",                 "Answer 4", 3, 10);    q7.setValues("Question : ", "Answer 1",                 "Answer 2", "Answer 3",                 "Answer 4", 3, 10);    q8.setValues("Question : ", "Answer 1",                 "Answer 2", "Answer 3",                 "Answer 4", 3, 10);    q9.setValues("Question : ", "Answer 1",                 "Answer 2", "Answer 3",                 "Answer 4", 3, 10);    q10.setValues("Question : ", "Answer 1",                  "Answer 2", "Answer 3",                  "Answer 4", 3, 10);     q1.askQuestion();    q2.askQuestion();    q3.askQuestion();    q4.askQuestion();    q5.askQuestion();    q6.askQuestion();    q7.askQuestion();    q8.askQuestion();    q9.askQuestion();    q10.askQuestion();     // Display the total score    cout << "Total Score = " << Total         << "out of 100" << endl;     // Display the results     // If the player pass the quiz    if (Total >= 70) {        cout << "Congrats you passed the"             << " quiz!" << endl;    }     // Otherwise    else {        cout << "Alas!
