Question

Tasks You are going to build a program that generates a random integer between 1 and 10, then prompts user to make several guesses of the number until user gets the right number - For each guess, tell user if the guess is higher or lower than the number - Handle the potential exception with user guess.

Use visual studio C#

// do comment if any problem arises

// code

using System;

class test

{

    static void Main()

    {

        Random random = new Random();

        // guess a number between 1 and 10

        int guess = random.Next(1, 10);

        Console.WriteLine("Welcome!  Guess the number I'm thinking of.  It is between 1 and 10");

        int user_guess;

        // loop till user guesses correct guess

        while (true)

        {

            Console.Write("\nPlease enter a number between 1 and 10: ");

            // use exception for user input

            try

            {

                user_guess = Int32.Parse(Console.ReadLine());

            }

            catch (Exception)

            {

                Console.WriteLine("Error, please enter an integer.");

                continue;

            }

            if (user_guess > guess)

            {

                Console.WriteLine("Your guess is too high.  Please try again");

            }

            else if (user_guess < guess)

            {

                Console.WriteLine("Your guess is too low.  Please try again");

            }

            else

            {

                Console.WriteLine("\nYou won the game!   The correct number was " + guess);

                break;

            }

        }

    }

}

Output:

Welcome! Guess the number I'm thinking of. It is between 1 and 10 Please enter a number between 1 and 10: abc Error, please enter an integer. Please enter a number between 1 and 10: 5 Your guess is too high. Please try again Please enter a number between 1 and 10: 2 You won the game! The correct number was 2
