C语言，为什么较大N不正确

Question

#include<stdio.h>
int main()
{
int n;
scanf("%d", &n);
double sum = 0.0;
double a;
double max = 0.0;
double min = 10.0;
for (int i = 1; i <= n; i++)
{
scanf("%lf", &a);
sum += a;
if (a > max)
{
max = a;
}
if (a < min)
{
min = a;
}
}
double average = (sum - max - min) / (n - 2);
printf("%.2lf", average);
return 0;
}

Answer 1

max和min 不能赋值。 在读入数之后再赋值
