编写程序从键盘得到三个整数，找出其中的最大数(升级版)

升级版：

指针变量和对应的存储区进行捆绑

程序中经常只关心和指针捆绑的存储区的某种特征而不关心他的来源

#include<stdio.h>int main(void){int num = 0,num1 = 0,num2 = 0;int *p_max = &num,*p_mid = &num1,*p_min = &num2;printf("请输入三个整数：");scanf("%d %d %d",&num,&num1,&num2);//交换p_max和p_midif(*p_mid > *p_max){int *p_tmp = p_max;p_max = p_mid;p_mid = p_tmp;}//交换p_max和p_minif(*p_min > *p_max){int *p_tmp = p_max;p_max = p_min;p_min = p_tmp;}//交换p_min和p_midif(*p_min > *p_mid){int *p_tmp = p_mid;p_mid = p_min;p_min = p_tmp;}printf("%d %d %d \n",*p_min,*p_mid,*p_max);return 0;}
