To get a feel for J, I'm implementing FizzBuzz, but I keep getting a control
error.
#!/usr/bin/env jconsole
div3 =: 0 = 3 & |
div5 =: 0 = 5 & |
div35 =: div3 *. div5
fizzy =: 3 : 0
if. div35 & do.
'FizzBuzz'
elseif. div3 & do.
'Fizz'
elseif. div5 & do.
'Buzz'
elseif. 1 do.
> 'd' (8!:0) &
end.
)
fizzy 1
exit ''
Cheers,
