 using namespace std;
typedef struct NODE
{
    int number;
    string name;
    string sex;
    int age;
    struct NODE *pNext;
}*PNODE,node;

void travel_List(PNODE pHead)
{

    PNODE p=pHead->pNext;
    while(NULL!=p)
    {
        cout<<p->number<<" ";
        cout<<p->name<<" ";
        cout<<p->sex<<" ";
        cout<<p->age<<" ";
        p=p->pNext;
    }
    cout<<endl;

}
PNODE create_list(void)
{
    PNODE pHead=new node;

    PNODE pTail=pHead;
    pTail->pNext=NULL;

    for(int i=0; i<=1; i++)
    {
        int num;
        string nm;

        pTail=pNEW;
    }
    return pHead;

}
int main()
{

    PNODE pHead=NULL;
    pHead=create_list();
    travel_List(pHead);

}
