generate random number and compare to user input

[fatimahtaher]

Hi,

I am supposed to create a program that generates a random number and then asks the user to guess the number (1-100). The program tells the user if he guessed too high or too low. If he guessed right, it asks the user is he/she wants to play again. If the answer is yes, it generates a random number and asks the user to guess the number again. The user can exit if he enters 0. I have created the following code so far but it does not work. I would appreciate any help.

static void Main(string[] args)
      {
         
         Random randomNumbers = new Random();
         int secretNumber = randomNumbers.Next(1,101);
         double enterNum = 0;

         do
         {
            
                    
            // pick random number from 1 to 100
            
            Console.Write("{0} ", secretNumber);

            //get input
            Console.WriteLine("Please enter a number from 1 to 100 (O to quit)", enterNum);
            enterNum = Convert.ToDouble(Console.ReadLine());

         //loop when the generated number is not equal to the number entered by user
         }
         while (secretNumber != enterNum)
         {

               while (enterNum != 0)
               
                  //if the random number is less that the number entered by user
                  if   (secretNumber > enterNum)
                  Console.WriteLine("Your guess is too low.", enterNum);

                  //if the random number is more than the number entered by the user
                  else if (secretNumber < enterNum)
                  Console.WriteLine("Your guess is too high.", enterNum);

               
         }
          
          
            //if the random number is equal to the number entered by user
            if (secretNumber == enterNum)
            {
               Console.WriteLine(" You got it right.");

               do
               {
                  //ask to play again
                  string decision;

                  Console.Write("Do you want to play again (yes/no)? ");
                  decision = Console.ReadLine();
               }

               while (decision != "yes")
               {
                  // Create random number generator
                  Random randomNumbers = new Random();

                  //declare variable to store random number
                  int secretNumber;
                  double enterNum;


                  //initialize variables
                  enterNum = 0;


                  // pick random number from 1 to 100
                  secretNumber = randomNumbers.Next(1, 101);
                  Console.Write("{0} ", secretNumber);

                  //get input
                  Console.WriteLine("Please enter a number from 1 to 100 (O to quit)",enterNum);
                  enterNum = Convert.ToDouble(Console.ReadLine());

               }
            }

         Console.WriteLine("Thank you for playing.");


         }
      }
   }

This looks like C# code, am I correct?
What doesn't work about this code?
Are you getting any compiler errors?

And next time, please post all of your code in [CODE ] [/CODE ] brackets!

[fatimahtaher]

Yes, it is C#. It does not like my nest while loops. It thinks it is a statement and expects me to put a semicolon at the end of the while statement.

Sorry about the code not being in the code brackets. Didn't know I had to do that.

Yes I can see that it would reject this code.
The first while statement is being read as the end of the do_while pair so the compiler wants to see a semicolon

do
         {
            
                    
            // pick random number from 1 to 100
            
            Console.Write("{0} ", secretNumber);

            //get input
            Console.WriteLine("Please enter a number from 1 to 100 (O to quit)", enterNum);
            enterNum = Convert.ToDouble(Console.ReadLine());

         //loop when the generated number is not equal to the number entered by user
         }
         while (secretNumber != enterNum)
         {

               while (enterNum != 0)

This is also the case for the next do statement

do
               {
                  //ask to play again
                  string decision;

                  Console.Write("Do you want to play again (yes/no)? ");
                  decision = Console.ReadLine();
               }

               while (decision != "yes")
               {

The compiler is expecting a matching while statement which should terminate with a semicolon

How do I fix it? Have been working on it all week and I have lost all objectivity.
