fizzbuzz

A try at writing some obfuscated "pretty" C, using the classic easy problem FizzBuzz

Programs

C89 pyramid

            i,t,f,j;
           p(char c){
          putchar(c);}
         g(){for(j=j^j;
        j++<2;0)p(122);}
       main(){char s[3]={
      37,100,21^21};while(
     i++<25<<2){if((t=i%3)*
    (f=i%5))printf(s,i);if(!
   t){p('\a'*10);p(0x69);g();
  }if(!f){p(0x42);p('2'*2+'"'/
 2);g();;}j=i<<5;while(--j!='('
>>2);p(j);}puts("Am I hired?");}

Modern hexagon

This works without exploiting C89, including stdio.h properly and using explicit types.

      #include<stdio.h>
     int i,t,f,j; void p
    (char c){putchar(c);}
   void g(){for(j=j^j;j++<
  2;0)p(122);}int main(void
 ){char s[3]={37,0x64,21^21}
;while(i++<25<<2){if((t=i%3)*
 (f=i%5))printf(s,i);if(!t){
  p('\a'*10);p(0x69);g();;}
   if(!f){p(0x42);p('2'*2+
    '"'/2);g();}j=i<<5;do
     ;while(--j!='('>>2)
      ;p(j);}return 0;}

It works on Hackerrank!

Building and running

The Makefile allows you to build using

make

upon which you can run using

./fizzbuzz

If you wish to install (why?) don't forget to set DESTDIR and PREFIX before running

make install

If you use Nix (yay), simply use the standard new commands like

nix build
nix run
