Question

Create a new console application (using the .NET Framework and not .NET Core). Name your project and solution RandomGuess. Generate a random number between 1 and 100, using the Random (Links to an external site.) class. Prompt the user to guess the random number until they successfully guess it.

Extra's:

• Allow the user to input the range for the random number (between X and Y)
• Validate that the user actually input a valid number, if they did not, prompt them to input a valid number

Program:

using System;
                  
public class Program
{
   public static void Main()
   {
       Random r = new Random();
       int randomNum = r.Next(1, 100);
       Console.WriteLine("Enter your guess between 1 and 100: ");
       int userGuess = Convert.ToInt32(Console.ReadLine());
       while(userGuess!=randomNum)
       {
           Console.WriteLine("Sorry! Invalid guess. Please enter a valid guess between 1 and 100: ");
           userGuess = Convert.ToInt32(Console.ReadLine());
           if(userGuess==randomNum)
           {
               Console.WriteLine("Congrats!!! you guessed right");
               break;
           }
       }
   }
}
