求助！麻烦各位帮忙看看这段程序问题出在哪了，非常感谢！

main()
{ int cocks=0,hens,chicks;
   while(cocks<=19)
    {hens=0;
    while(hens<=33)
      {chicks=100-cocks-hens;
       if(5.0*cocks+3.0*hens+chicks/3==100.0
         printf("%d%d%d\n",cocks,hens,chicks);
       hens++
      }
     cocks++
    }
 getchar();
 system("pause");
}
