Some languages automatically insert a newline after outputting a string, unless measures are taken to prevent its output.

Task

Display the string Goodbye, World! without a trailing newline.

68000 Assembly

Because assembly lets (or rather forces) the programmer to create their own print routines, new lines are not done by default.

Code is called as a subroutine, taking A0 as its argument (e.g. LEA myString,A0 JSR PrintString). The hardware-specific PrintChar routine is left unimplemented. <lang 68000devpac>PrintString:

input: A0 = source address
outputs to screen.

MOVE.B (A0)+,D0 BEQ Terminated JSR PrintChar BRA PrintString Terminated:

If this routine did in fact put a new line by default, it would do so here with the following
MOVE.B #13,D0 ;13 is ascii for Carriage Return (moves cursor back to beginning of row).
JSR PrintChar
MOVE.B #10,D0 ;10 is ascii for Line Feed (moves cursor down one line).
JSR PrintChar

Goodbye, World!

This example will implicitly include a final, implementation defined, terminator (usually a linefeed) if the output is a file (RM A.10.7-8) such as stdout on UNIX systems. <lang ada> with Ada.Text_IO;

procedure Goodbye_World is begin

  Ada.Text_IO.Put("Goodbye, World!");

end Goodbye_World; </lang> Using Ada.Text_IO.Text_Streams instead allows us to control the termination. <lang ada> with Ada.Text_IO; with Ada.Text_IO.Text_Streams;

procedure Goodbye_World is

   stdout: Ada.Text_IO.File_Type := Ada.Text_IO.Standard_Output;

begin

   String'Write(Ada.Text_IO.Text_Streams.Stream(stdout), "Goodbye World");

BASIC

BaCon

BaCon supports BASIC PRINT ending with trailing semicolon to prevent a newline and also supports a FORMAT clause that uses printf specifications and special character escapes (with no \n, there is no newline). <lang freebasic>PRINT "Goodbye, World!"; PRINT "Goodbye, World!" FORMAT "%s"</lang>

Applesoft BASIC

<lang ApplesoftBasic>PRINT "GOODBYE, WORLD!";</lang>

Commodore BASIC

<lang basic>10 print chr$(14) : rem Switch to lower+uppercase character set 20 print "Goodbye, World!"; 30 rem * If we end this program here, we will not see the effect because 40 rem BASIC will print 'READY' at a new line anyway. 50 rem * So, we just print additional message... 60 print "(End of the world)" 70 end</lang> Output:

Batch File

Under normal circumstances, when delayed expansion is disabled
The quoted form guarantees there are no hidden trailing spaces after World! <lang dos><nul set/p"=Goodbye, World!" <nul set/p=Goodbye, World!</lang>

If delayed expansion is enabled, then the ! must be escaped
Escape once if quoted form, twice if unquoted. <lang dos>setlocal enableDelayedExpansion <nul set/p"=Goodbye, World^!" <nul set/p=Goodbye, World^^^!</lang>

BBC BASIC

<lang bbcbasic> REM BBC BASIC accepts the standard trailing semicolon:

     PRINT "Goodbye World!";
     
     REM One could also output the characters individually:
     GW$ = "Goodbye World!"
     FOR i% = 1 TO LEN(GW$)
       VDU ASCMID$(GW$, i%)
     NEXT</lang>

Bc

<lang Bc>print "Goodbye, World!"</lang>

beeswax

<lang beeswax>_`Goodbye, World!</lang>

beeswax prints everything without appending a newline character. beeswax has an instruction to explicitely print a newline character: N.

Befunge

In Befunge, a newline has to be explicitly output when required, so you can just not include one if it's not wanted.

<lang befunge>"!dlroW ,eybdooG">:#,_@</lang>

bootBASIC

"Goodbye, w" and "orld!" are printed on different lines because not enough characters are allowed per line to complete this task in one line, even for the most code golfed version. <lang bootBASIC>10 print "Goodbye, w"; 20 print "orld!";</lang>

Bracmat

<lang bracmat>put$"Goodbye, World!"</lang>

Brainf***

One option was to copy the code from the regular Hello World version and omit the last period, but one of the nicer things about the language is that no matter how simple your program is, if it's more than a few characters long, it's probably unique. So here's yet another version of Goodbye, World in Brainf***. <lang bf>>+++++[>++++>+>+>++++>>+++<<<+<+<++[>++>+++>+++>++++>+>+[<]>>-]<-]>> +.>>+..<.--.++>>+.<<+.>>>-.>++.[<]++++[>++++<-]>.>>.+++.------.<-.[>]<+.[-] [G oo d b y e , W o r l d !]</lang>

C

In C, we do not get a newline unless we embed one: <lang c>#include <stdio.h>

include <stdlib.h>

int main(int argc, char *argv[]) {

 (void) printf("Goodbye, World!");    /* No automatic newline */
 return EXIT_SUCCESS;

}</lang>

However ISO C leaves it up to implementations to define whether or not the last line of a text stream requires a new-line. This means that the C can be targetted to environments where this task is impossible to implement, at least with a direct text stream manipulation like this.

C#

<lang csharp>using System;

class Program {

   static void Main(string[] args)
   {
       //Using Console.WriteLine() will append a newline
       Console.WriteLine("Goodbye, World!");

       //Using Console.Write() will not append a newline
       Console.Write("Goodbye, World!");

<lang Forth>\ The Forth word ." does not insert a newline character after outputting a string ." Goodbye, World!"</lang>

Fortran

<lang Fortran>program bye

 write (*,'(a)',advance='no') 'Goodbye, World!'

end program bye</lang>

The "advance" facility was introduced with F90, as was the ability to specify format instructions (the '(A)' part) without a separate FORMAT statement. Earlier, there was a common extension: <lang Fortran> WRITE (6,1) "Goodbye, World!"

   1 FORMAT (A,$)
     END</lang>

In this, the FORMAT instruction is to accept alphabetic text (the A) from the WRITE statement, followed by the special $ item (of no mnemonic form) which signified that there was not to be any new line action at the end of the output. This sort of thing is useful when writing a prompt to the screen so that the input of the response appears on the same screen line. The text could also have been incorporated into the FORMAT statement, which would be useful if there were many WRITE statements scattered about that were to send forth the same text.

These facilities only became of interest when, instead of card decks and lineprinters, I/O involved a keyboard and screen with both input and output appearing on the same screen. Thus, in earlier Fortran usage, the issue would not arise for output to a lineprinter, because it was already the case: a line written to the lineprinter was not followed by a end-of-line/start-new-line sort of action by the lineprinter. It stayed put on the line just written. It was the following output to the lineprinter that would state "advance one" (or two, or, no) lines at the start of its output. This was the "carriage control character", and a 1 signified "skip to top-of-form" which is to say, start a new page.

In other words, the Fortran approach for output was <carriage control><output text> rather than the <output text><carriage control> sequence, that now has to be suppressed by the "advance = 'no'" facility.

Icon and Unicon

Native output in Icon and Unicon is performed via the write and writes procedures. The write procedure terminates each line with both a return and newline (for consistency across platforms). The writes procedure omits this. Additionally, the programming library has a series of printf procedures as well. <lang Icon>procedure main()

  writes("Goodbye, World!")

J

On a linux system, you can use 1!:3 because stdout is a file: <lang j> 'Goodbye, World!' 1!:3 <'/proc/self/fd/1' Goodbye, World! </lang> However, J works in environments other than Linux, so... Solution:prompt from the misc package. Example:<lang j> load 'general/misc/prompt'

  prompt 'Goodbye, World!'

Goodbye, World!</lang> Notes: J programs are normally run from a REPL, or session manager, which comes in several flavors. The traditional commandline-based terminal (jconsole), one of several desktop applications (jqt for the current version of J, jgtk and jwd for older but still supported versions), a web-based frontend (jhs), and various mobile apps (J for iOS, Android).

The specific session manager being used changes the context and therefore answer to this task. For example, when using J from a browser (including mobile browsers) newlines are omitted by default. Further, J provides strong tools for coalescing results and manipulating them prior to output, so newline elimination would typically happen before output rather than after.

With that said, prompt handles the most common cases (using binary output for jconsole, so no newline is appended; adjusting the REPL prompt in the desktop apps to to elide the newline which is normally included by default, etc).

For truly automated processes, you'd almost always want this kind of functionality (omitting the newline when printing) in a file- or stream-oriented application. For those cases, the simple text 1!:3 file will append the text to the referenced file verbatim, without inserting any extra newlines.

So, if a J programmer were asked to solve this task, the right approach would be to ask why that is needed, and then craft a solution appropriate to that situation.

jq

The "-j" command-line option suppresses the newline that would otherwise be printed, e.g. if "$" is the command-line prompt: <lang sh>$ jq -n -j '"Goodbye, World!"' Goodbye, World!$ </lang> The trailing "$" is the command-line prompt.

Similarly: <lang sh>$ echo '"Goodbye, World!"' | jq -j Goodbye, World!$ </lang>

init(nil: ref Draw->Context, nil: list of string) { sys = load Sys Sys->PATH; sys->print("Goodbye, World!"); # No automatic newline. }</lang>

LLVM

<lang llvm>; This is not strictly LLVM, as it uses the C library function "printf".

LLVM does not provide a way to print values, so the alternative would be
to just load the string into memory, and that would be boring.

$"OUTPUT_STR" = comdat any @"OUTPUT_STR" = linkonce_odr unnamed_addr constant [16 x i8] c"Goodbye, World!\00", comdat, align 1

--- The declaration for the external C printf function.

declare i32 @printf(i8*, ...)

define i32 @main() {

Logtalk

No action is necessary to avoid an unwanted newline. <lang logtalk>

ML/I

Simple solution

In ML/I, if there isn't a newline in the input, there won't be one in the output; so a simple solution is this (although it's hard to see that there isn't a newline). <lang ML/I>Goodbye, World!</lang>

Modula-2

N/t/roff

By default, /.ROFF/ replaces single non-consecutive newline characters with spaces, but considers two consecutive newline characters as a paragraph separator and omits 2-newline's worth of spaces. The former behaviour is the same as in HTML and Rosettacode's Wiki syntax: text on non-consecutive single newlines get wrapped on the same line above it. In /.ROFF/, this is the default behaviour if and only if the typesetter is processing the input in fill mode (.fi); though, by default, the typesetter processes in this mode anyway!

Because /.ROFF/ is a document formatting language, most text input is expected to be text input which will get output on paper, so there is usually no need to run a special procedure or routine to output text.

<lang N/t/roff> Goodbye, World! </lang>

Nanoquery

<lang nanoquery>print "Goodbye, world!"</lang>

Neko

The Neko builtin $print does not add a newline.

REXX

It should be noted that upon a REXX program completion, any text left pending without a C/R (or newline) is followed by a
blank line so as to not leave the state of the terminal with malformed "text lines" (which can be followed by other text
(lines) from a calling program(s), or the operating system (shell) which is usually some sort of a "prompt" text string. <lang rexx>/*REXX pgm displays a "Goodbye, World!" without a trailing newline. */

Transact-SQL

This example is incorrect. Please fix the code and remove this message.

Details: output isn't consistent with the task's requirements: wrong word.

As an output statement, PRINT always adds a new line <lang Transact-SQL> PRINT 'Goodbye, World!'</lang> or: As a result set <lang Transact-SQL> select 'Goodbye, World!'</lang>

TUSCRIPT

<lang tuscript> $$ MODE TUSCRIPT PRINT "Goodbye, World!" </lang> Output:

Goodbye, World!

TXR

Possible using access to standard output stream via TXR Lisp: <lang bash>$ txr -e '(put-string "Goodbye, world!")' Goodbye, world!$</lang>

UNIX Shell

The echo command is not portable, and echo -n is not guaranteed to prevent a newline from occuring. With the original Bourne Shell, echo -n "Goodbye, World!" prints -n Goodbye, World! with a newline. So use a printf instead.

Works with: Bourne Shell

<lang bash>printf "Goodbye, World!" # This works. There is no newline. printf %s "-hyphens and % signs" # Use %s with arbitrary strings.</lang>

Unfortunately, older systems where you have to rely on vanilla Bourne shell may not have a printf command, either. It's possible that there is no command available to complete the task, but only on very old systems. For the rest, one of these two should work:

<lang bash>echo -n 'Goodbye, World!'</lang> or <lang bash>echo 'Goodbye, World!\c'</lang>

The print command, from the Korn Shell, would work well, but most shells have no print command. (With pdksh, print is slightly faster than printf because print runs a built-in command, but printf forks an external command. With ksh93 and zsh, print and printf are both built-in commands.)

Works with: ksh93

Works with: pdksh

Works with: zsh

<lang bash>print -n "Goodbye, World!" print -nr -- "-hyphens and \backslashes"</lang>

C Shell

C Shell does support echo -n and omits the newline.

<lang csh>echo -n "Goodbye, World!" echo -n "-hyphens and \backslashes"</lang>

Ursa

Ursa doesn't output a newline to an I/O device by default, so simply omitting an endl object at the end of the output stream is all that's needed. <lang ursa>out "goodbye world!" console</lang>

Verbexx

<lang verbexx>@STDOUT "Goodbye, World!";</lang>

Verilog

<lang Verilog>module main;

   begin
     $write("Goodbye, World!");
     $finish ;
   end

endmodule</lang>

Vim Script

<lang vim>echon "Goodbye, World!"</lang>

Visual Basic .NET

<lang vbnet>Module Module1

   Sub Main()
       Console.Write("Goodbye, World!")
   End Sub

End Module</lang>

Web 68

This example is incorrect. Please fix the code and remove this message.

Details: output isn't consistent with the task's requirements: wording, punctuation.

Use the command 'tang -V hello.w68', then 'chmod +x hello.a68', then './hello.a68'

<lang web68>@ @a@=#!/usr/bin/a68g -nowarn@>@\BEGIN print("Hello World") END</lang>
