标题: 取地址与空函数
#include<stdio.h>
void mikado (int);

int main (void)
{
int pooh = 2, bah = 5;

printf ("In main (), pooh = %d and &pooh = %p\n",
   pooh, &pooh);
printf ("In main (), bah = %d and &bah = %p\n",
   bah,&bah);

mikado (pooh);
return 0;
}

void mikado (int bah)
{
int pooh = 10;

printf ("In main (), pooh = %d and &pooh = %p\n",
   pooh, &pooh);
printf ("In main (), bah = %d and &bah = %p\n",
   bah, &bah);
}
