将三个整数由大到小输出

#include<stdio.h>
#include<stdlib.h>
int main()
{
 int a = 0;
 int b = 0;
 int c = 0;
 int max = 0;
 scanf("%d %d %d", &a, &b, &c);
 if (a < b)
 {
  max = a;
  a = b;
  b = max;
 }
 if (a<c)
 {
  max = a;
  a = c;
  c = max;
 }
 if (b<c)
 {
  max = b;
  b = c;
  c = max;
 }
 printf("三个数从大到小的顺序是：%d, %d, %d", a, b, c);
 printf("\n");
 system("pause");
 return 0;
}
