The problem of insert term.

[JYT-ad]

I try to use the function KukuTable::insert with my txt file, but it cannot work.
Could you tell me the reason

The error is as follow.

/home/jiang/My_Project/cuckoo_hash_table/cuckoo_hash.cpp: In function ‘int main(int, char**)’:
/home/jiang/My_Project/cuckoo_hash_table/cuckoo_hash.cpp:49:31: error: cannot call member function ‘bool kuku::KukuTable::insert(kuku::item_type)’ without object
49 | KukuTable::insert(term);
| ^

int main(int argc, char *argv[])
{
    auto table_size = static_cast<table_size_type>(atoi(argv[1]));
    auto stash_size = static_cast<table_size_type>(atoi(argv[2]));
    uint8_t loc_func_count = static_cast<uint8_t>(atoi(argv[3]));
    item_type loc_func_seed = make_random_item();
    uint64_t max_probe = static_cast<uint64_t>(atoi(argv[4])); 
    item_type empty_item = make_item(0, 0);                  

    KukuTable table(table_size, stash_size, loc_func_count, loc_func_seed, max_probe, empty_item);

    ifstream in("test.txt");
    string line;
    char p[64];

    if (!in)
    {
        cout << "File cannot open!" << endl;
    }

    **while (getline(in, line))
    {
        strcpy(p, line.c_str());
        item_type term= make_item(reinterpret_cast<unsigned char*>(p));
        KukuTable::insert(term);
    }**

    print_table(table);

    return 0;
}

Sorry for the late reply. You might have solved this already, but the problem is that the insert method should be called on your "table" object:

table.insert(term);
