Obfuscated C code...
https://www.ioccc.org/years.html 
Wish I was smart enough to write code like that and enter into the contest...
Look at this amazing code! "Amazing" in the sense of "wow, this is really clever", not in the sense of "you should write like that"...
int i;main(){for(;i["]<i;++i){--i;}"];read('-'-'-',i+++"hell\
o, world!\n",'/'/'/'));}read(j,i,p)void*i;{write(j/p+p,i---j,(int)i/(int)i);}
@vaporeon_ i really want to know why read and write can be used in reverse like that
spoilers
@aescling Look closely. They're defining a function read(j,i,p) that performs a write!
