C# Repeating a Loop Based on User Input

Question

I'm working on a C# assignment and am pretty much done, except I cannot figure out how to replay the loop based on the user answering "yes" or "no." If they answer yes I want the loop to replay, if they answer no, it will leave a nice goodbye message.

Here's my code (deleted my commenting for simplicity):

Random randomNumber = new Random();

        int count = 0;
        int actualNumber = randomNumber.Next(1, 50);
        int userGuess = 0;
        bool correct = false;


        Console.WriteLine("In this program you will be prompted to guess a number between 1 and 50 \n\n" +
            "I'll help by saying if your guess is higher/lower than the actual number\n\n\n\n" +
            "I'm thinking of a number between 1 and 50, please enter your guess.\n\n");


        while (!correct)
            {
                count++;

                Console.Write("Guess: ");
                string input = Console.ReadLine();

                if (!int.TryParse(input, out userGuess))
                {
                    Console.WriteLine("That's not a number between 1 and 50, please try again.");
                    continue;
                }

                if (userGuess < actualNumber)
                {
                    Console.WriteLine("Sorry, the number is higher than that, keep guessing!");
                }
                else if (userGuess > actualNumber)
                {
                    Console.WriteLine("Sorry, the number is lower than that, keep guessing!.");
                }
                else
                {
                    correct = true;
                    Console.WriteLine("{0} is the right number! It took you         {1} times to guess", userGuess, count);
                }
            }

I'm having trouble figuring out if I should use another while statement or an if/else or what and where to use it. I've searched here and found similar questions for different languages, but nothing for C#. I would appreciate any help. Thanks!

Answer 1

You can place your code inside do-while loop. And it will ask from user if he or she wants to replay? And if user enters Yes , then the game will start again.

Random randomNumber = new Random();

do
{  
    int actualNumber = randomNumber.Next(1, 50);
    int count = 0;
    int userGuess = 0;
    bool correct = false;

    Console.Clear();
    Console.WriteLine("In this program you will be prompted to guess a number between 1 and 50 \n\n" +
"I'll help by saying if your guess is higher/lower than the actual number\n\n\n\n" +
"I'm thinking of a number between 1 and 50, please enter your guess.\n\n");

    while (!correct)
    {
         // ...your code
    }

    Console.WriteLine("Do you want to replay?");
} while (Console.ReadLine().ToUpper() == "YES");

PS: Initilize Random outside the loop as example in above, otherwise it will generate same number.
