C语言程序设计教程（第三版）课后习题10.1 （三目运算符解决）

我这样写有什么问题吗？
include <stdio.h>
void main()
{
	int a[3];
	int i, j, t;
	printf("please 3 number\n");
	for(i=0; i<3; i++)
	{
		scanf("%d", &a[i]);
	}
	for(i=0; i<2; i++)
	{
		for(j=0; j<2-i; j++)
		{
			if(a[j] > a[j+1])
			{
				t = a[j];
				a[j] = a[j+1];
				a[j+1] = t;
			}
		}
	}
	printf("排序后:\n");
	for(i=0; i<3; i++)
	{
		printf("%d", a[i]);
	}
	printf("\n");
}

#include<stdio.h>
int s(int x,int y)
{
    if(x>y)return x;
    else return y;
}
int s1(int x,int y)
{
    if(x>y)return y;
    else return x;
}
int s2(int x,int y,int z)
{
    if(x>y&&y>z)return y;
    else if(x>z&&z>y)return z;
    else return x;
}
int main()
{
    int a,b,c,d,e;
    scanf("%d %d %d", &a, &b,&c);
    d=s(s(a,b),s(b,c));
    e=s1(s1(a,b),s1(b,c));
    printf("%d %d %d",e,s2(a,b,c),f);
    return 0;
}

大佬三目看不懂啊

#include <stdio.h>
void paixu(int a, int b, int c);
int main()
{
	int a, b, c;
	scanf("%d %d %d",&a, &b, &c);
	paixu(a, b, c);

	return 0;

}

void paixu(int a, int b, int c)
{
	int t, k, m;
	 if(a > b)
	 	t = a;
	 else
	 	t= b;
	 if(c > t)
	 	k = c;
	 else
	 	k = t;
	 
	 if(k = c)
	 {
		if(a > b)
		{
		 	t = a;
			m = b;
		}
	 	else
	 	{
		 	t= b;
			m = a;
	 	}
	 }
	 if(k == b)
	 {
		if(a > c)
		{	t = a;
			m = c;
		}
			
		else
		{
			t = c;
			m = a;
		}
			
	 }

	 if(k == a)
	 {
		if(b > c)
		{
			t = b;
			m = c;
		}
		else
		{
			t = c;
			m = b;

		}
			
	 }
	 printf("%d %d %d\n", k ,

#include <stdio.h>

int main()
{
	int a,b,c;
	int t;
	scanf("%d %d %d",&a,&b,&c);
	if(a>b)
	{
		t=a;
		a=b;
		b=t;
	}
	if(a>c)
	{
		t=a;
		a=c;
		c=t;
	}
	if(b>c)
	{
		t=b;
		b=c;
		c=t;
	}
	printf("%d %d %d",a,b,c);
	
	return 0;
	
}

#include<stdio.h>
int main()
{
	int a, b,c,s;
	scanf("%d%d%d", &a, &b,&c);
	if (a < b)
		s = a, a = b, b = s;
	if (a < c)
		s = a, a = c, c = s;
	if (b < c)
		s = b, b = c, c = s;
 	printf("%d %d %d ", c,b,a);
	return 0;
}

#include<stdio.h>
int main()
{
    int a,b,c;
    if(scanf("%d%d%d",&a,&b,&c)){
    if(a<b&&b<c)
    {
    printf("%d%d%d\n",a,b,c);
    }
    else if(a<c&&c<b)
    { 
    printf("%d%d%d\n",a,c,b);
    }
    else if(b<a&&a<c)
    {
    printf("%d%d%d\n",b,a,c);
    }
    else if(b<c&&c<a)
    {
    printf("%d%d%d\n",b,c,a);
    }   
    else if(c<a&&a<b)
    {
    printf("%d%d%d\n",c,a,b);
    }
    else
    printf("%d%d%d\n",c,b,a);
    }
    return 0;
}
想知道错哪了

int main(){
	int a, b, c;
	scanf("%d%d%d", &a, &b, &c);
	int min, mid, max;
	min = (a<b?a:b)<c?(a<b?a:b):c;
	max = (a>b?a:b)>c?(a>b?a:b):c;
	mid = (a+b+c) - min - max;
	printf("%d %d %d", min, mid, max); 
	return 0;
}
