C++ Coding Challenge: Hello World without IDE or code editor

Question

Pretty much what the title says. Create a fully functional program that prints the below string *verbatim*:

Hello World!

Rules:
*. You cannot use a text editor of any kind.
*. You cannot use an IDE (obviously).
*. Only an executable binary must be left.
*. The executable must run immediately and automatically during the process. In other words, it cannot require you double-click it or such, it must just run as if you pressed "Compile & Run" in an IDE.
*. The least number of steps wins.
*. You may write it in C or C++.
*. Your solution does *not* have to be agnostic/universal/portable.
*. Don't cheat by looking for an answer, you'll spoil ler fun.

Good luck!

Answer 1

Input format? Explain?

[Can be done with standard system utils, possibly anywhere, but definitely on all or most *nix environments with a single line from the shell].

Answer 2

Does linux console count as a text editor if I do not use vim, emacs and so on ?

Answer 3

@Baptiste Nope, a regular console isn't a text editor.

*If it's a shell.

Answer 4

My input (on linux minth 17) :
printf "#include <stdio.h>\nint main(){printf("Hello World");return 0;}" > __file__tmp__.c
gcc __file__tmp__.c -o _hello__
./_hello__
rm _hello__ __file__tmp__.c

All done in one line :
alias super_hello='printf "#include <stdio.h>\nint main(){printf(\"Hello World\");return 0;}" > __file__tmp__.c;gcc __file__tmp__.c -o _hello__;./_hello__;rm _hello__ __file__tmp__.c'

But it is neither portable, nor fancy, nor a good practice :p

simply remove "alias super_hello=' " and " ' " at the beginning and at the end to compile execute without having to type the name super_hello

Answer 5

Ahaha nice !

And what is the input format please ?
