segment tree implimentation

void seg_ment(int node,int b,int e){
    if(b==e){
        segment_tree[node]=A[b];
    }
    else{
        int left=2*node,right=2*node+1;
        seg_ment(left,b,(b+e)/2);
        seg_ment(right,(b+e)/2 +1,e);
        int lcontent=segment_tree[left],rcontent=segment_tree[right];
        segment_tree[node]=lcontent+rcontent;
        printf("%d ",segment_tree[node]);
    }
}

if any error plz tell me
