today, my cc can't make '__in64'

it's so bad!!!

i don't know why

#include <stdio.h>
//long long num[100000+100];
__int64 num[+];
__int64 res;
//long long res;
int main(){long long res;
    int n,i;
    int left[+];
    int right[+];
    int t;
    while(~scanf("%d",&n)&&n){
        res=;
        for(i=;i<=n;++i){
            scanf("%I64d",&num[i]);
        }
        left[]=;
        right[n]=n;
        for(i=;i<=n;++i){
            t=i;
            while(t>&&num[i]<=num[t-]){
                t=left[t-];
            }
            left[i]=t;
        }
        for(i=n-;i>=;--i){
            t=i;
            while(t<n&&num[i]<=num[t+]){
                t=right[t+];
            }
            right[i]=t;
        }
        res=;
        for(i=;i<=n;++i){
            if((right[i]-left[i]+)*num[i]>res)
                res=(right[i]-left[i]+)*num[i];
        }
        printf("%I64d\n",res);
//        printf("%lld\n",res);
    }
    return ;
}
