/**

 Guessing Game 

Write an interactive Java program called GuessingGame.java

It starts by choosing a random number between 0 and 1023
(inclusive), then repeatedly prompts the player to enter 
a guess at the number. 

If the player guesses the correct number, 
a congratulatory message is printed. 
Otherwise, the program just displays a
message saying whether the player's number 
was too high or too low. The goal is to guess 
the number in as few tries as possible. 

Here is an example of a game: 

      I'm thinking of a number between 0 and 1023.
      Can you guess it? 500
        No!  Too low.
      Can you guess it?  600 
        No!  Too high.
      Can you guess it?  550 
        No!  Too high.
      Can you guess it?  530 
        YES!  YOU GOT IT IN 4 TRIES!

For the first version of your program have 1024 as the default max, 
but in a second version also allow the user to supply another max
as a command-line argument, if they want to.

Reading from standard-input is actually rather tricky
in Java, so you may find the following helpful:
*/

import java.io.*;

public class GuessingGame {

    public static void main(String[] args) 
    {
        int max = 1024; 

	BufferedReader input = 
	    new BufferedReader(new InputStreamReader(System.in));


        // YOUR CODE HERE for allowing different max value
        // to be supplied on the command line


        // lookup Math.random() in the online docu
	int target = (int)(max * Math.random());

	//
        // YOUR CODE HERE
        //

    }


    public static int getIntPrompted(String prompt, BufferedReader input) 
    {
	try {
	    System.out.print(prompt);
	    String text = input.readLine();
	    return Integer.parseInt(text);
	} catch (Exception e) {
	    System.out.println(" That was not a proper number, try again.");
	    return getIntPrompted(prompt,input);
	} 
    }
}
