Please help me with the task: Guess what

C# with Love
1

Hello, I’m working on this task:

You have a guessing game written by a talented (but inexperienced) student who didn’t know about exceptions. She used int.Parse but didn’t handle situations when the input is invalid. For example, if instead of a number the input was !@#, the program crashes.
Your task is to add two try-catch constructions: one in the beginning, when the user inputs the secret number that we’ll guess, and one to cover each guessed number. If the user’s input appears to be invalid, output “Your input is invalid. Try once again!”. Keep asking the user to input a number until they input a valid number. Here is an example:
Input a secret number
>Hello!
Your input is invalid. Try once again!
>100
Now start guessing
>What am I supposed to do? !@#
Your input is invalid. Try once again!
>99
Bigger
>101
Smaller
>I’m tired
Your input is invalid. Try once again!
>100
You’ve guessed! Woohoo!

Here is my code:


namespace Exceptions
{
   public class GuessWhat
   {

       public static void Main()
       {
           Console.WriteLine("Input a secret number");

           while (true)
           {
               try
               {
                   var secretNumber = int.Parse(Console.ReadLine());
                   GuessingGame(secretNumber);
                   break;
               }
               catch
               {

                   Console.WriteLine("Your input is invalid. Try once again!");
               }
           }
       }

       private static void GuessingGame(int secretNumber)
       {
           Console.WriteLine("Now start guessing");
           var guessed = false;
          
           while (!guessed)
           {

               try
               {
                   var number = int.Parse(Console.ReadLine());


                   if (number > secretNumber)
                       Console.WriteLine("Smaller");
                   else
                       Console.WriteLine("Bigger");
                   if (number == secretNumber)
                   {
                       guessed = true;
                       Console.WriteLine("You've guessed! Woohoo!");
                       
                   }

               }

               catch

               {

                   Console.WriteLine("Your input is invalid. Try once again!");
               }

           }

              
       }
   }
}

Can anyone please help me to solve it?

when you type the right number, you’ll always print “Bigger”. You just need to add an else if(condition) and it will solve everything!

I really like the solution though :slight_smile:

Thank you :heart_eyes: I, as usual, was looking for the problem in the wrong place :laughing:
