Guess the number

Guess the number
You are encouraged to solve this task according to the task description, using any language you may know.

Task

Write a program where the program chooses a number between   1   and   10.

A player is then prompted to enter a guess.   If the player guesses wrong,   then the prompt appears again until the guess is correct.

When the player has made a successful guess the computer will issue a   "Well guessed!"   message,   and the program exits.

A   conditional loop   may be used to repeat the guessing until the user is correct.

ZX Spectrum Basic has no conditional loop constructs, so we have to emulate them here using IF and GO TO.

20 INPUT "Guess a number that's between 1 and 10: ",g
30 IF g=n THEN PRINT "That's my number!": STOP
40 PRINT "Guess again!"
50 GO TO 20

BASIC256

n = int(rand * 10) + 1
print "I am thinking of a number from 1 to 10"
do
   input "Guess it > ",g
   if g <> n then
      print "No luck,  Try again."
   endif
until g = n
print "Yea! You guessed my number."

Batch File

At the line set /a answer=%random%%%(10-1+1)+1, if you want to change the minimum and maximum numbers, change all number ones (not counting the one that is in 10) to your desired chosen number and for the maximum, which is 10, do the same, but for maximum (eg. the minimum could be 123 and the maximum could be 321, etc.).

@echo off
set /a answer=%random%%%(10-1+1)+1

if %guess%==%answer% (echo Well guessed!
pause) else (set /p guess=Nope, guess again:

The value is generated by the clk function, which returns a (probably) non-integral rational number. The den function retrieves the denominators of this number. The rational number, multiplied by its denominator, becomes an natural number.

Java

Works with: Java version 6+

public class Guessing {
    public static void main(String[] args) throws NumberFormatException{
        int n = (int)(Math.random() * 10 + 1);
        System.out.print("Guess the number between 1 and 10: ");
        while(Integer.parseInt(System.console().readLine()) != n){
            System.out.print("Wrong! Guess again: ");
        }
        System.out.println("Well guessed!");
    }
}

For pre-Java 6, use a Scanner or BufferedReader for input instead of System.console() (see Input loop#Java).

JavaScript

function guessNumber() {
  // Get a random integer from 1 to 10 inclusive
  var num = Math.ceil(Math.random() * 10);
  var guess;

  while (guess != num) {
    guess = prompt('Guess the number between 1 and 10 inclusive');
  }
  alert('Congratulations!\nThe number was ' + num);
}

guessNumber();

Requires a host environment that supports prompt and alert such as a browser.

jq

Works with: jq version 1.5

jq currently does not have a built-in random number generator, so a suitable PRNG for this task is defined below. Once `rand(n)` has been defined, the task can be accomplished as follows:

{prompt: "Please enter your guess:", random: (1+rand(9)) }
| ( (while( .guess != .random; .guess = (input|tonumber) ) | .prompt),
  "Well done!"

Invocation

With the program as given here in a file named program.jq, a seed must be specified on the command line as illustrated on the following line:

   $ jq -nr -f program.jq --arg seed 17

PRNG

# LCG::Microsoft generates 15-bit integers using the same formula
# as rand() from the Microsoft C Runtime.
# Input: [ count, state, random ]
def next_rand_Microsoft:
  .[0] as $count
  | ((214013 * .[1]) + 2531011) % 2147483648 # mod 2^31
  | [$count+1 , ., (. / 65536 | floor) ];

def rand_Microsoft(seed):
  [0,seed]
  | next_rand_Microsoft  # the seed is not so random
  | next_rand_Microsoft | .[2]; 

# A random integer in [0 ... (n-1)]:
def rand(n): n * (rand_Microsoft($seed|tonumber) / 32768) | trunc;

Jsish

From Javascript entry.

function guessNumber() {
    // Get a random integer from 1 to 10 inclusive
    var num = Math.ceil(Math.random() * 10);
    var guess;
    var tries = 0;
 
    while (guess != num) {
        tries += 1;
        printf('%s', 'Guess the number between 1 and 10 inclusive: ');
        guess = console.input();
    }
    printf('Congratulations!\nThe number was %d   it took %d tries\n', num, tries);
}

if (Interp.conf('unitTest')) {
    // Set a predictable outcome
    Math.srand(0);
    guessNumber();
}

/*

Julia

Works with: Julia version 0.6

function guess()
    number = dec(rand(1:10))
    print("Guess my number! ")
    while readline() != number
        print("Nope, try again... ")
    end
    println("Well guessed!")
end

guess()

Output:

Guess my number! 1
Nope, try again... 2
Nope, try again... 3
Nope, try again... 4
Nope, try again... 5
Nope, try again... 6
Nope, try again... 7
Nope, try again... 8
Nope, try again... 9
Nope, try again... 10
Well guessed!

	do { print(" Your guess : ") } while (n != readLine())
	println("\nWell guessed!")

Sample input/output:

 Your guess : 5
 Your guess : 8

Mercury

Mercury does have a 'time' module in its standard library, but it offers an abstract type instead of the seconds-since-the-epoch we want to seed the RNG with. So this is also an example of how easy it is to call out to C. (It's just as easy to call out to C#, Java, and Erlang.) Also, rather than parse the input, this solution prepares the random number to match the typed input. This isn't a weakness of Mercury, just the author's desire to cheat a bit.

Wait for the escape key.
Shut down.

To play guess the number:
Pick a secret number between 1 and 10.
Write "I picked a secret number between 1 and 10." to the console.
Loop.
Write "What is your guess? " to the console without advancing.
Read a number from the console.
If the number is the secret number, break.
Repeat.
Write "Well guessed!" to the console.

UNIX Shell

#!/bin/sh
# Guess the number
# This simplified program does not check the input is valid

# Use awk(1) to get a random number. If awk(1) not found, exit now.
number=`awk 'BEGIN{print int(rand()*10+1)}'` || exit

until read guess; [ "$guess" -eq "$number" ]

  echo 'Sorry, the guess was wrong! Try again!'
done
echo 'Well done! You guessed it.'

An older version used while [ "$guess" -ne "$number" ]. With pdksh, input like '+' or '4x' would force the test to fail, end that while loop, and act like a correct guess. With until [ "$guess" -eq "$number" ], input like '+' or '4x' now continues this until loop, and acts like a wrong guess. With Heirloom's Bourne Shell, '+' acts like '0' (always a wrong guess), and '4x' acts like '4' (perhaps correct).
