入力3整数を実装し、昇順で出力します

#include<stdio.h>
int main()
{
	int a, b, c;
	printf("请输入三个整数：");
	scanf("%d%d%d", &a, &b, &c);//输入三个整数
	if (a < b) //b小于a时，a值不变；b大于a时，b值赋给a，a值赋给b
	{
		int ret = a;
		a = b;
		b = ret;
	}
	if (a < c)
	{
		int ret = a;
		a = c;
		c = ret;
	}
	if (b < c)
	{
		int ret = b;
		b = c;
		c = ret;
	}
	printf("从大到小排序为：%d %d %d", a, b, c);//将三个整数从大到小排序
	return 0;
