这个用c语言怎么写，求解答！

#include <stdio.h>
int getMaxMin(int a,int b,int flag)
{
      if(flag == 1)
      {
          if(a>b)
              return a;
          return b;
      }
      if(a<b)
          return a;
      return b;
}
int main()
{
    int a,b,c;
    scanf("%d%d%d",&a,&b,&c);
    printf("%d %d",getMaxMin(getMaxMin(a,b,1),c,1),getMaxMin(getMaxMin(a,b,0),c,0);
    return 0;
}

#include <stdio.h>

int main()
{
    int a,b,c;
    int max,min;
    scanf("%d %d %d",&a,&b,&c);
    if(a >b && a > c)
        max = a;
    else if( b > a && b > c)
        max = b;
    else
        max = c;

    if(a<b && a < c)
        min = a;
    else if(b<a && b < c)
        min = b;
    else
        min = c;
    printf("%d %d",max,min);
    return 0;
}

#include<stdio.h>
#include<math.h>
int main()
{
    int a, b, c;
    int max = 0;
    int min = 0;
    scanf("%d %d %d",&a,&b,&c);
    
    // 打擂台开始
    if(a > b)
    {
        max = a;
        min = b;
    }
    else
    {
        max = b;
        min = a;
    }
    if(c > max)
        max = c;
    if(c < min)
        min = c;
    
    printf("max = %d",max);
    printf("\nmin = %d",min);
    
 
    return 0;
}
