指针练习一

#include<stdio.h>/*练习指针：通过指针变量求三个整数中的最大数和最小数。*/void main(){int a, b, c;int *pmax, *pmin;//pmax变量中存放最大数的地址，pmin变量中存放最小数的地址。printf("please input three numbers:\n");scanf("%d%d%d",&a,&b,&c);if(a > b){pmax = &a;pmin = &b;}else{pmax = &b;pmin = &a;}if(c > *pmax){pmax = &c;}else if(c < *pmin){pmin = &c;}printf("max = %d\nmin = %d\n",*pmax, *pmin);}
