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

 

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.

//Using Console.WriteLine() will append a newline

In Graphical User Interface Support Script, we specify a newline, if we want one. The following will not produce a newline:

 

 

 

 

 

 

 

=={{header|Icon}} and {{header|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.

writes("Goodbye, World!")

A trailing semicolon prevents a newline

 

 

=={{header|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).

===More sophisticated solution===

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

module Hello

{

// as with C#, Write() does not append a newline

 

// equivalently

Write("Goodbye, ");

In OCaml, the function <code>[http://caml.inria.fr/pub/docs/manual-ocaml/libref/Pervasives.html#VALprint_endline print_endline]</code> prints a string followed by a newline character on the standard output and flush the standard output. And the function <code>[http://caml.inria.fr/pub/docs/manual-ocaml/libref/Pervasives.html#VALprint_string print_string]</code> just prints a string with nothing additional.

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:

 

or

 

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.)

C Shell does support <code>echo -n</code> and omits the newline.
