输入三个数，按照从大到小排列用程序写出来

#include<stdio.h>
int main()
{
	int a = 0;
	int b = 0;
	int c = 0;
	scanf_s("%d%d%d", &a, &b, &c);
	if (a < b)
	{
        int num = 0;
		num = a;
		a = b;
		b = num;
	}
	if (a < c)
	{
		int sum = 0;
		sum = a;
		a = c;
		c = sum;

	}
	if (c > b)
	{
		int mat = 0;
		c = mat;
		c = b;
		b = mat;

	}
	printf("%d %d %d\n", a, b, c);

以上是这道题的代码，有更加简便的可以评论讨论一下，给我更多的建议，谢谢大家
