Help me!!!

#include<cstdio>
double a[305];
int main(){
    int b;
    scanf("%d",&b);
    int c=0;//计数变量
    double d=0.0,e=10000.0,f=0.0;
    while(c<b){
        scanf("%lf",&a[c]);
        if(a[c]<e) e=a[c];//求最小
        if(a[c]>f) f=a[c];//求最大
        d+=a[c];//求总和
        c++;
    }
    printf("%.2f %.2f\n",(d-e-f)/b,d/b-((d-e-f)/b));//输出
    return 0;
}
