using System;

class Program

// Quiz questions
string[] questions = {
"What is the capital of France?",
"Who is the author of 'To Kill a Mockingbird'?",
"What is the result of 2 + 2 * 2?",
"Which of the following is not a primitive data type in C#?"

{"A. int", "B. string", "C. float", "D. boolean"}
};

// Correct answers
string[] answers = {"B", "B", "A", "B"};

// Initialize variables for score and user's answer
int score = 0;
string userAnswer;

// Loop through each question
for (int i = 0; i < questions.Length; i++)
{
// Display the question
Console.WriteLine(questions[i]);

// Display the options
for (int j = 0; j < 4; j++)
{
Console.WriteLine(options[i, j]);
}

// Prompt the user for an answer
Console.Write("Enter your answer (A, B, C, or D): ");
userAnswer = Console.ReadLine().ToUpper();

// Check if the answer is correct
if (userAnswer == answers[i])
{
Console.WriteLine("Correct!");
score++;
}
else
{
Console.WriteLine("Incorrect!");
}

Console.WriteLine();
}

// Display the final score
Console.WriteLine("Your final score is: " + score + "/" + questions.Length);
