【C语言】【指针】对输入的两个整数按大小输出

#include <stdio.h>

int main()

{

void swap(int* p1, int* p2);

int  a, b;

int* pointer_1, * pointer_2;

printf("Please neter a and b:\n");

scanf("%d%d", &a, &b);

pointer_1 = &a;

pointer_2 = &b;

if (a < b)  swap(pointer_1, pointer_2);

printf("max=%d,min=%d\n", *pointer_1, *pointer_2);

return 0;

}

void swap(int* p1, int* p2)

{

int temp;

temp = *p1;

*p1 = *p2;

*p2 = temp;

}
