从键盘上输入两个数，按小大的顺序输出

#include <stdio.h>

#include <stdlib.h>

int main()

{

int num1,num2;

int *num1_p=&num1,*num2_p=&num2,*pointer;

printf("Input the first number:");

scanf("%d",num1_p);

printf("Input the second number:");

scanf("%d",num2_p);

printf("num1=%d,num2=%d\n",num1,num2);

if(*num1_p>*num2_p)

{

pointer=num1_p;

num1_p=num2_p;

num2_p=pointer;

}

printf("min=%d,max=%d",*num1_p,*num2_p);

return 0;

}
