Goodbye Cruel World!

Question

Background

Hello golfers! I would like to learn all the programming languages! But I kinda have a short attention span... and copying all the Hello World examples gets boring... but I like fire! ^w^

Challenge

So here is the plan! I want you all to write the smallest code that will compile, print Goodbye Cruel World!, and then crash. Or, as a bonus twist challenge, print Hello World! and crash with Goodbye Cruel World!

Rules

• Your score will be total character count used. The answer must be a whole executable program.
• Your program must print Goodbye Cruel World! to output, and then crash (unexpected error).
  • For a score bonus, you must print Hello World! to output instead, but the error message must also contain Goodbye Cruel World!. If you complete the bonus challenge, you may divide your score by 2. (Include a ! at the end of your score if you are claiming the bonus!)
• As long as the standard output still prints, and standard error still prints, the order doesn't matter. Just as long as neither can block the other from happening.
• The output must contain the contents of the above; " shouldn't appear in the output.
• The output should contain the specified string, and nothing else.
• The crash report can contain anything, but to claim the bonus, the following regex should match /Goodbye Cruel World!/mi (aka, contains, ignore case/surrounding text))
• The strings Hello World! and Goodbye Cruel World! are case insensitive, but otherwise should appear exactly as above.
• If the language is capable of crashing (it cannot change its exit code), it needs to crash. Otherwise use the standard "error report" (i.e., STDERR) for the language.

I can crash Python 3, so I have included an example Python 3 answer! Now lets all set the world on fire! ^W^

Answer 1

Kitanai (28 bytes)

print"Goodbye Cruel World!"z

It just prints "Goodbye Cruel World!" then tries to call unknown function z (so it crashes)

Answer 2

Lua, 47 / 2 == 23 bytes

Prints "Hello World!" to STDOUT, then crashes with "Goodbye cruel world!" and a stack trace to SDTERR.

print"Hello World!"
error"Goodbye cruel world!"

JavaScript 58 bytes , with bonus 58/2 = 29 bytes

console.log("Hello World!");
throw "Goodbye Cruel World!"

Very Straightforward , I have crashed the program with the "Good Bye Cruel World!" error.

EDIT : Thanks to eithed and Erik the OutGolfer , Saved 36 bytes !. Hope this method still works for the challenge

Answer 7

J, 28 Bytes

=:echo'Goodbye cruel world!'

Echoes 'Goodbye cruel world!', and then encounters a syntax error when theres no variable to assign the result (an empty list) to.

Example:

   =:echo'Goodbye cruel world!'
Goodbye cruel world!
|syntax error
|   =:echo'Goodbye cruel world!'

Answer 8

Java 8, 108 bytes, score 54!

interface M{static void main(String[]a){System.out.print("Hello World!");new Byte("Goodbye Cruel World!");}}

Try it online here.

This solution attempts to create a Byte from the given String and crashes since "Goodbye Cruel World!" cannot be evaluated to an integer value.

Java 8, 93 bytes (no bonus)

interface M{static void main(String[]a){System.out.print("Goodbye Cruel World!");int i=0/0;}}

This is pretty straightforward as well. It crashes upon trying to divide by zero.

println("Goodbye Cruel World!");int b=1/0;

First try at using Processing for a golfing challenge. Couldn't figure out a way for the bonus challenge since Processing is very good at finding errors before you run your code!

Run and debug it

It's a compressed string literal, followed by a packed Qe. Q peeks and outputs, and e is eval, which fails.

Answer 16

05AB1E (legacy), score: 13.5 13 11.5 (23 bytes / 2 for bonus)

…Ÿ™‚ï!“‚¿bye±ƒuel‚ï!“.ǝ

Try it online.

-1.5 (-3 bytes) thanks to @Grimy.

Outputs in full lowercase.

05AB1E (legacy) is unable to exit with an error as far as I know (unless there is a bug in its source code), so instead this will print hello world! to STDOUT and goodbye cruel world! to STDERR.

Explanation:

…                 # Three lowercase dictionary-compressed words with space delimiter
 Ÿ™               #  "hello"
   ‚ï             #  "world"
     !            #  Literal "!"
“             “   # Push dictionary string in lowercase with automatic space-delimiter:
 ‚¿bye±ƒuel‚ï!    #  "goodbye cruel world!"
               .ǝ # Print to STDERR
                  # And print the top of the stack to STDOUT implicitly

See this 05AB1E this of mine (section How to use the dictionary?) to understand why …Ÿ™‚ï! is hello world! and “‚¿bye±ƒuel‚ï!“ is goodbye cruel world!.

---

05AB1E, score: 11.5 (23 bytes / 2 for bonus)

…Ÿ™‚ï!,“‚¿bye±ƒuel‚ï!“F

Unlike the legacy version, the new version is able to error out sometimes. The difference between the above program are:

• The ,, which is an explicit print with trailing newline
• And F instead of .ǝ, which is a ranged loop and will error because the "goodbye cruel world!" is not an integer:

(RuntimeError) Could not convert goodbye cruel world! to integer.

Answer 17

ink, 44! bytes

VAR a="Goodbye Cruel World!"
Hello World!->a

Try it online!

Funnily enough, even though variables created in VAR declarations are usually always available even if the VAR statement is unreachable, this program only "works" if that VAR statement comes before the divert - if it doesn't, it's a syntax error instead.

Answer 18

Ruby, 41 bytes / 2 = 20.5 bytes!

"Goodbye Cruel World!"&$><<"Hello World!"

Try it online!

$><< is a very useful method of output for Ruby golfing--syntax around it is very forgiving("Goodbye Cruel World!"&puts"Hello World!" would be a syntax error, for example, rather than the runtime exception we need), and << has medium precedence so we can control when it executes more freely.

Sadly, the fact that we have to encode "Goodbye, cruel world!" makes this very long.

Answer 24

JavaScript, 51 / 2 = 25.5! 43 / 2 = 21.5!

"Goodbye Cruel World!"(console.log("Hello World!"))

console.log can be changed to alert and ("") to backticks saving 8 bytes (but I'm not sure this is eligible):

"Goodbye Cruel World!"(alert`Hello World!`)

Answer 27

Mathematica, 23! Bytes

Print["Hello World!"]/."Goodbye Cruel World!";

Prints the first string then attempts to use the second string as a replacement rule which it isn't so crashes (throws an error message which is equivalent to a crash in Mathematica).

Output:

Hello World

ReplaceAll::reps: {Goodbye Cruel World!} is neither a list of replacement rules nor a valid dispatch table, and so cannot be used for replacing. >>

Answer 28

C, 42 bytes

Not shorter than Steadybox's C answer, but more resistant to optimization.

main(){ftw(puts("Goodbye Cruel World!"));}

ftw has a short name and its first parameter is a pointer, so the return value from puts makes it crash.
