[Error] expected primary-expression before ']' token怎么解决

#include<stdio.h>
int typeN(int list[], int n, int lenth) {
    list[]={6,5,9,8,2,1,7,3,4};
    int S1[100], S2[100];
    int sum1 = 0, sum2 = 0;
    int i = 0;
    int a= list[0];
    
    for (i = 0; i < lenth; i++) {
        if (list[i] > a)
        {
            S1[sum1++] = list[i];    
        }
        else if (list[i] < a)
        {
            S2[sum2++] = list[i];
        }
    }
    printf("%d",S1);
}

你这个没写main函数啊
给你改了下：

#include<stdio.h>
int main() {
    int list[20]={6,5,9,8,2,1,7,3,4},lenth=9;
    int S1[100], S2[100];
    int sum1 = 0, sum2 = 0;
    int i = 0;
    int a= list[0];
    for (i = 0; i < lenth; i++) {
        if (list[i] > a)
        {
            S1[sum1++] = list[i];
        }
        else if (list[i] < a)
        {
            S2[sum2++] = list[i];
        }
    }
    printf("%d",S1);
}
