The task is to produce a sequential count in octal, starting at zero, and using an increment of a one for each consecutive number. Each number should appear on a single line, and the program should count until terminated, or until the maximum value that can be held within the system registers is reached (for a 32 bit system using unsigned registers, this value is 37777777777 octal).
AWK
The awk extraction and reporting language uses the underlying C library to provide support for the printf command. This enables us to use that function to output the counter value as octal:
<lang awk>BEGIN {
for (l = 1; l < 2147483647; l++) { printf("%o\n", l); }
}</lang>
C++
This prevents an infinite loop by counting until the counter overflows and produces a 0 again. This could also be done with a for or while loop, but you'd have to print 0 (or the last number) outside the loop.
<lang cpp>#include <iostream>
- include <iomanip>
using namespace std;
int main() {
unsigned i = 0; do { cout << setbase(8) << i << endl; ++i; } while(i != 0);
}</lang>
Fortran
<lang fortran>program Octal
implicit none integer, parameter :: i64 = selected_int_kind(18) integer(i64) :: n = 0
! Will stop when n overflows from ! 9223372036854775807 to -92233720368547758078 (1000000000000000000000 octal)
do while(n >= 0) write(*, "(o0)") n n = n + 1 end do
end program</lang>
Icon and Unicon
<lang unicon>link convert # To get exbase10 method
procedure main()
limit := 8r37777777777 every write(exbase10(seq(0)\limit, 8))
end</lang>
Java
<lang java>public class Count{
public static void main(String[] args){ for(int i = 0;i <= Integer.MAX_VALUE;i++){ System.out.println(Integer.toOctalString(i)); //optionally use "Integer.toString(i, 8)" } }
}</lang>
Lua
<lang lua>for l=1,2147483647 do
print(string.format("%o",l))
end</lang>
Modula-2
<lang modula2>MODULE octal;
IMPORT InOut;
VAR num : CARDINAL;
BEGIN
num := 0; REPEAT InOut.WriteOct (num, 12); InOut.WriteLn; INC (num) UNTIL num = 0
END octal.</lang>
Perl 6
<lang perl6>say .fmt: '%o' for 0 .. *;</lang>
PicoLisp
<lang PicoLisp>(for (N 0 T (inc N))
(prinl (oct N)) )</lang>
Python
<lang Python>import sys for n in xrange(sys.maxint):
print oct(n)</lang>
Tcl
<lang tcl>package require Tcl 8.5; # arbitrary precision integers; we can count until we run out of memory! while 1 {
puts [format "%llo" [incr counter]]
}</lang>
UNIX Shell
We use the bc calculator to increment our octal counter:
<lang sh>#!/bin/sh num=0 while true; do
echo $num num=`echo "obase=8;ibase=8;$num+1"|bc`
done</lang>
