![Task](http://static.miraheze.org/rosettacodewiki/thumb/b/ba/Rcode-button-task-crushed.png/64px-Rcode-button-task-crushed.png)
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.

jq
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

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
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.

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).
