Interpreting a benchmark in C, Clojure, Python, Ruby, Scala and others [closed]

Answer 1

Don't forget Fortran! (Mostly joking, but I would expect similar performance to C). The statements with exclamation points are optional, but good style. (! is a comment character in fortran 90)

logical function isprime(n)
IMPLICIT NONE !
integer :: n,i
do i=2,n
   if(mod(n,i).eq.0)) return .false.
enddo
return .true.
end

subroutine findprimes(m)
IMPLICIT NONE !
integer :: m,i
logical, external :: isprime

do i=11,m
   if(isprime(i) .and. isprime(i-6))then
      write(*,*) i-6,i
   endif
enddo
end

program main
findprimes(10*1000)
end
