I have the following code. This is a simple quiz. I need to score this quiz. How do I add how many answers were correct in percent at the end?

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks;

namespace Quiz { class Program { static void Main(string[] args) { string choice; //Intro text do { Console.WriteLine("Created by Brandon Borin"); Console.WriteLine("Welcome to the Math QUIZ!"); Console.WriteLine("ENGR115: CheckPoint 2"); //multiple choice question Console.WriteLine(" Question 1.

Console.WriteLine(" "); Console.WriteLine("Please input A, B, C, or D."); //this is where you read what the user inputs and assign it to a new string string answer1 = Console.ReadLine();

//deciding answer based on input if (answer1.ToUpper() == "D") { Console.WriteLine("***Correct!***"); Console.WriteLine(" Next Question..."); } else { Console.WriteLine("***Wrong!***"); Console.WriteLine(" Next Question..."); } //True or False question Console.WriteLine(" Question 2.
