    }while(flag);

    return;
}

    int flag = 1;
    do{
        printf("%s\n", end->name);
        if(end->backward == NULL){
            flag = 0;
        }
        end = end->backward;

    Memb memb1;
    Memb memb2;
    Memb memb3;

    Memb *end;

    Memb membNum[] = {memb1, memb2, memb3};
    char *membName[] = {"lina", "mina", "bina"};
    int size = sizeof(membName)/sizeof(membName[0]);
    for(int i = 0; i < size; i++){
        strcpy(membNum[i].name, *(membName + i));
    }

    start = &membNum[0];
    start->forward = &membNum[1];
    start->forward->forward = &membNum[2];
    start->forward->forward->forward = NULL;

    end = &membNum[2];
    end->backward = &membNum[1];
    end->backward->backward = &membNum[0];
    end->backward->backward->backward = NULL;

    printf("Names of members (forward traversing): \n");
    showForward(start);
    printf("\nNames of members (backward traversing): \n");
    showBackward(end);

    return 0;
}

代码非常简单，就不多说了
