思路

代码

#define _CRT_SECURE_NO_WARNINGS 1
#include<stdio.h>

//键盘输入4个整数，从小到大排序
int main()
{
	int n1, n2, n3, n4;
	scanf_s("%d %d %d %d", &n1, &n2, &n3, &n4);

	if (n1 > n2)
	{
		int tmp = n1;
		n1 = n2;
		n2 = tmp;
	}

	if (n1 > n3)
	{
		int tmp = n1;
		n1 = n3;
		n3 = tmp;
	}

	if (n1 > n4)
	{
		int tmp = n1;
		n1 = n4;
		n4 = tmp;
	}

	if (n2 > n3)
	{
		int tmp = n2;
		n2 = n3;
		n3 = tmp;
	}

	if (n2 > n4)
	{
		int tmp = n2;
		n2 = n4;
		n4 = tmp;
	}
	if (n3 > n4)
	{
		int tamp = n3;
		n3 = n4;
		n4 = tamp;
	}

	printf("%d %d %d %d ", n1, n2, n3, n4);
	return 0;
}

运行结果
