程序代码：

int i=0;
main()
{ int i=5;
   reset(i/2); printf("i=%d\n",i);
   reset(i=i/2); printf("i=%d\n",i);
   reset(i/2); printf("i=%d\n",i);
   workover(i); printf("i=%d\n",i);
}
workover(int i)
{ i=(i%i)*((i*i)/(2*i)+4);
  printf("i=%d\n",i);
  return(i);
}
reset(int i)
{ i=i>=2?5:0;
  return(i);
}
