输入三个数字，按从大到小的顺序输出

#include<stdio.h>

int main()
{
	int a = 0;
	int b = 0;
	int c = 0;
	scanf("%d%d%d", &a, &b, &c);//2 1 3
	if (a < b)
	{
		int tmp = a;
		a = b;
		b = tmp;
	}
	if (a < c)
	{
		int tmp = a;
		a = c;
		c = tmp;
	}
	if (b < c)
	{
		int tmp = b;
		b = c;
		c = tmp;
	}
	printf("%d %d %d",a,b,c);
	return 0;
}
