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!" to the terminal, preventing a trailing newline from occuring.

C
In C, we do not get a newline unless we embed one:
<lang c>#include <stdio.h>
int main(int argc, char *argv[]) {
(void) printf("Goodbye, World!"); /* No automatic newline */ return EXIT_SUCCESS;
}</lang>
GUISS
In Graphical User Interface Support Script, we specify a newline, if we want one, so this will not produce a newline:
<lang GUISS>Start,Programs,Accessories,Notepad,Type:Goodbye World[pling]</lang>
Perl
<lang perl>print "Goodbye World!"; # A newline does not occur automatically</lang>
UNIX Shell
The behaviour of echo command is inconsistent across implementations. The -n parameter is not guaranteed to prevent a newline from occuring, so use a printf instead:
<lang sh>echo -n "Goodbye World!" # This may not work printf "Goodbye World!" # This works. newline is not automatically produced</lang>
