Great that i <3 u...

The funny part was supposed to be the mushrooms.... nevermind.
I guess i should have said that he is 14.

[kazymjir]

Mushrooms are very good
Unfortunately, it's not season for shrooms.




This one is good

[Brainsaw]

Hello World? Need vacation

[kazymjir]

Brainsaw, are you sure?

[pippy3]

Code: Select all

a: 
   goto a

I think it will get into an infinite loop.

[Brainsaw]

Brainsaw, are you sure?

Just a wild guess . It does, however, almost look as good as the "hello world" of Brainfuck

This picture is very trickery.
All people is starting to analysis those hexadecimal ascii values, but...
look at printf function.
Is there something missing?

[hybrid]

why would you need a separate format string when you already built one? Should work without any problems.

[kazymjir]

Ok, I will give you solution.
This code will output... an error.
Why? Because printf() is in stdio.h, which is not included in this code

Solutions of most problems are very easy, but human perception always looking for complex solutions, not seeing simple patterns.

[hybrid]

No, that's an incomplete answer. The thing is that the output of this function was searched. It's also called _tmain, which will probably also not link without a proper main(). But you could still define the output of this function in case it's called (which would also require that it's properly linked before).

Put aside all the sophistry and it actually says "Hello World"

Code: Select all

#include <stdio.h>

int main()
{
  char* p=new char[12];*p=0x48;++p;*p=0x65;++p;*p=0x6c;
  ++p;*p=0x6c;++p;*p=0x6f;++p;*p=0x20;++p;*p=0x57;++p;
  *p=0x6f;++p;*p=0x72;++p;*p=0x6c;++p;*p=0x64;++p;
  *p=0x0;--p;--p;--p;--p;--p;--p;--p;--p;--p;--p;--p;

  printf(p);
  delete p;

  return 0;
}

[kazymjir]

It's also called _tmain, which will probably also not link without a proper main().

_tmain is used in VC++. _t* functions is calling ANSI functions if _UNICODE isn't defined. If _UNICODE is defined, it's calling UNICODE version of that function.
So everything is ok, proper main will be called (main if ANSI, wmain if UNICODE).
But, there don't even must be main() function. Why?
Because, compiler is working always first. If compiler found error in code, it will not run linker.

So, output will be an error that printf() function is not found.
Linker will be not called, because of error found by compiler in code

Here is my optimized version:

Code: Select all

  #include <stdio.h>

int main() {
  char *p=new char[13];
  *p++=0x48;*p++=0x65;*p++=0x6c;*p++=0x6c;*p++=0x6f;
	*p++=0x20;*p++=0x57;*p++=0x6f;*p++=0x72;*p++=0x6c;*p++=0x64;*p++=0x0A;*p=0;
  --p;--p;--p;--p;--p;--p;--p;--p;--p;--p;--p;--p;printf(p);return 0;
}

[kazymjir]

Let's do more optimization!

Code: Select all

int main() {
	char *p=new char[13];
	*p++=0x48;*p++=0x65;*p++=0x6c;*p++=0x6c;*p++=0x6f;
	*p++=0x20;*p++=0x57;*p++=0x6f;*p++=0x72;*p++=0x6c;*p++=0x64;*p++=0x0A;*p=0;
	--p;--p;--p;--p;--p;--p;--p;--p;--p;--p;--p;--p;
	__asm__("\
		movl $4, %%eax\n\
		movl $0, %%ebx\n\
		push %0\n\
		pop %%ecx\n\
		movl $13,%%edx\n\
		int $0x80" : :"g"(p)); return 0;
}
