Zen is a general purpose programming language designed to build simple, reliable and efficient programs.
function factorial(n)
return n <= 1 then 1 else n * factorial(n - 1)
function main(...arguments)
var n = promptInteger('Enter an integer: ')
var result = factorial(n)
printf('%d! = %d', n, result)The above example generates the following output:
Enter an integer: 5
5! = 120
