# Guess the number

**Guess the number**

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

The task is to 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 guess wrong then the prompt appears again until the guess is correct. When the player has made a successful guess the computer will give a "Well guessed!" message, and the program will exit.

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

## Bracmat[edit]

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.

Guess: 2

Well guessed!

## Java[edit]

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[edit]

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.

## Julia[edit]

function guess()

number = rand(1:10)

print("Guess my number! ")

while(chomp(readline(STDIN)) != string(number))

print("Nope, try again! ")

end

println("Well guessed!")

end

- Output:

julia> guess() Guess my number! 6 Nope, try again! 9 Nope, try again! 45 Nope, try again! grr Nope, try again! 3 Well guessed!

## Lasso[edit]

### Command Line[edit]

The following example works when Lasso is called from a command line

local(

number = integer_random(10, 1),

status = false,

guess

)

// prompt for a number

stdout('Guess a number between 1 and 10: ')

while(not #status) => {

#guess = null

// the following bits wait until the terminal gives you back a line of input

while(not #guess or #guess -> size == 0) => {

#guess = file_stdin -> readSomeBytes(1024, 1000)

}

#guess = integer(#guess)

if(not (range(#guess, 1, 10) == #guess)) => {

stdout('Input not of correct type or range. Guess a number between 1 and 10: ')

else(#guess == #number)

stdout('Well guessed!')

#status = true

else

stdout('You guessed wrong number. Guess a number between 1 and 10: ')

}

}

### Web form[edit]

The following example is a web page form

<?LassoScript

local(

number = integer(web_request -> param('number') or integer_random(10, 1)),

status = false,

guess = web_request -> param('guess'),

_guess = integer(#guess),

message = 'Guess a number between 1 and 10'

)

if(not (range(#_guess, 1, 10) == #_guess)) => {

#Message = 'Input not of correct type or range. Guess a number between 1 and 10'

else(#_guess == #number)

#Message = 'Well guessed!'

#status = true

else

#Message = 'You guessed wrong number. Guess a number between 1 and 10'

}

## LOLCODE[edit]

There is no native support for random numbers. This solution uses a simple linear congruential generator to simulate them, with the lamentable restriction that the user must first be prompted for a seed.

## Mercury[edit]

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.

## UNIX Shell[edit]

#!/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

echo 'I have thought of a number. Try to guess it!'

echo 'Enter an integer from 1 to 10.'

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

do

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).

### C Shell[edit]

#!/bin/csh -f

# Guess the number

# jot(1) a random number. If jot(1) not found, exit now.

@ number = `jot -r 1 1 10` || exit

echo 'I have thought of a number. Try to guess it!'

echo 'Enter an integer from 1 to 10.'

@ guess = "$<"

while ( $guess != $number )

echo 'Sorry, the guess was wrong! Try again!'

@ guess = "$<"

end

echo 'Well done! You guessed it.'
