void help() {
    cout << "help" << endl;
}

int main(int argc, char* argv[])
{
    if (argc == 2) {
        if (strcmp(argv[1], "-help") == 0) {
            help();
        }
        else if (strcmp(argv[1], "-param_split") == 0) {
            char a[] = "-param1=aaa";
            char* param_right;
            char *ptr = strtok_s(a, "=", &param_right);
            cout << "a_left=" << a << endl;
            cout << "a_right=" << param_right << endl;
        }
    }
    else {
