Hello world/Newline omission

Hello world/Newline omission
You are encouraged to solve this task according to the task description, using any language you may know.

Some languages automatically insert a newline after outputting a string, unless measures are taken to prevent its output. The purpose of this task is to output the string "Goodbye, World!" without a trailing newline.

Batch File

Under normal circumstances, when delayed expansion is disabled
The quoted form guarantees there are no hidden trailing spaces after World!

<nul set/p"=Goodbye, World!"
<nul set/p=Goodbye, World!

If delayed expansion is enabled, then the ! must be escaped
Escape once if quoted form, twice if unquoted.

BBC BASIC

      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

C

In C, we do not get a newline unless we embed one:

#include <stdio.h>
 
int main(int argc, char *argv[]) {
  (void) printf("Goodbye, World!");    /* No automatic newline */
  return EXIT_SUCCESS;
}

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++

In C++, using iostreams, portable newlines come from std::endl. Non-portable newlines may come from using constructs like \n, \r or \r\n. If we don't use any of these, we won't get a newline.

#include <iostreams>
 
int main(int argc, char *argv[]) {
  std::cout << "Goodbye, World!";
}

C#

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

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.

procedure main()
   writes("Goodbye, World!")    
end

J

Interpreting this task in the context of J is problematic. For example, many people use J from a browser where newlines are omitted by default. Meanwhile the J interpreter prompt always begins on a new line, so in interactive use this task becomes meaningless. 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.

Nevertheless, text 1!:3 filereference will append to the referenced file without inserting any extra newlines (which might be /proc/self/stdout on linux -- though of course stdout would typically not be meaningful if J is running in the browser and is also of dubious usefulness if J is running in GTK -- still, it can be done, even if it's meaningless).

So, if a J programmer were asked to solve this task, the right approach would be to ask why that is needed, and then solve the real problem instead. 1!:3 might or might not be the right answer, depending on the real issue.

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).

Goodbye, World!

More sophisticated solution

To make it clearer, we can define an ML/I skip to delete itself and an immediately following newline.

MCSKIP " WITH " NL
Goodbye, World!""

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.

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

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

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:

echo -n 'Goodbye, World!'

or

echo 'Goodbye, World!\c'

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

print -n "Goodbye, World!"
print -nr -- "-hyphens and \backslashes"

C Shell

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

echo -n "-hyphens and \backslashes"
