Visual-Studio

The goalis to build a quiz that will keep score. However, after the first run through the user need to have a second go around for the questions answered wrong.
How do I....
1. buid a scorecard that will give only the number of correct answers out of 10, ie.. 2 of 10, 8 of 10.
2. Create a second run through for the questions that were answered wrong

<pre>using System;
using System.Linq;

namespace Checkpoint_3
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Quiz");
            //Variables
            bool answerCorrect = false; // will be used to evaluate if answer is correct or not
            string[] questions = { "2+2=", "4x5=", "8+2=", "2x100=", "3+3=", "2+100", "2-2=", "1+2=", "3x3=15", "45-5+8=48" }; // will be questions used on test. 8 Multiple choice and 2 true/false
            string[] answers = { "a.4 b.2 c.6 d. 10", "a.40 b.20 c.16 d. 11", "a.6 b.12 c.16 d. 10", "a.104 b.200 c.65 d. 102", "a.4 b.2 c.6 d. 10", "a.14 b.200 c.60 d. 102", "a.4 b.2 c.0 d. 10", "a.3 b.2 c.6 d. 102", "true false", " true false" }; // these will stand as answer bank for all questions
            string [] correctanswer = { "a", "b", "d", "b", "c", "d", "c", "a", "false", "true" }; //these are the correct answers to all the question. any other selections will be countd as incorrect
            int[] scoreCard = { }; // everyone starts with 0 correct out of ten. once quiz is completed score will be listed as 1-10. 
            
            
            

            //Welcome To Program
            Console.WriteLine("Ryan Hinds, ENGR101- Quiz");
            Console.WriteLine();


            
            for (int i = 0; i < 10; i++)
            {
                
                Console.WriteLine(questions[i]);
                Console.WriteLine();
                Console.WriteLine(answers[i]);
                Console.WriteLine("Answer");
               
                string input = Console.ReadLine(); char letter; char.TryParse(input, out letter);
                if (input==correctanswer[i])
                {
                    Console.WriteLine(" You Are Correct");
                    Addscore(scoreCard[i]);
                }
                else
                    Console.WriteLine("Wrong");
                


                    Console.WriteLine();
                Console.WriteLine();
                

            }
           

            Console.ReadKey();

        }

        
    }
}
