R, <= 32 (safe)
It outputs the following string (34 characters. I hope there isn't a more trivial way to print this!)
pi - 4*(4*atan(1/5) - atan(1/239))
Edit: Hints: (1) This is very crackable. (2) No mathematical calculations are involved. (3) The program that outputs this is 24 characters long.
To crack, search Google for pi - 4*(4*atan(1/5) - atan(1/239)) R language
. (String chosen so that searching for it doesn't give obvious references to R!) Note that this line appears in example(pi)
. Note that the text of the example will be outputted if you include the give.lines=T
option in example()
. Arrive at the solution:
cat(example(pi,g=T)[10])
