链栈的实现

拖了很久，还是把链栈写了。链栈基本操作与顺序栈差不多，可是链栈弹出的时候，太麻烦，需要遍历整个链栈一遍，所以时间复杂度大于顺序栈的操作。

#include <stdio.h> 
#include <stdlib.h>

#define STACK_INIT_SIZE 100
#define STACKINCREAMENT 10

#define OVERFLOW    -1
#define ERROR  0
#define OK 1

typedef int Status;
typedef int ElemType;

typedef struct Node
{
        ElemType data;
        Node *next;
} Node;

typedef struct stk
{
        Node* head;
        Node* tail;
}stk;

Status StackInit(stk &ss)
{
    ss.head = (Node*)malloc(sizeof(Node));
    if (ss.head == NULL) return 0;
    ss.tail = ss.head;
    return 1;
}

Status Push(stk &ss, ElemType e)
{
    Node *temp;
    temp = (Node*)malloc(sizeof(Node));
    if (temp == NULL) return 0;
    temp->data = e;
    ss.head->next = temp;
    ss.head = temp;
    return 1;
}

Status Top(stk &ss, ElemType &e)
{
    if (ss.head == ss.tail)
    return 0;
    e = ss.head->data;
    return 1;
}

Status Pop(stk &ss)
{
    if (ss.head == ss.tail)
    return 0;
    Node *temp;
    temp = ss.tail;
    while(1)
    {
            if (temp->next == ss.head)
            {
                          free(ss.head);
                          ss.head = temp;
                          break;
            }
            temp = temp->next;
    }
    return 1;
}

int main()
{
    stk ss;
    StackInit(ss); 
    printf("how many\n");
    int n, i, e; 
    scanf("%d", &n); 
    for (i = 0;i < n; i++)
    {
        scanf("%d", &e);
        Push(ss,e);         
    } 
    for (i = 0; i < n; i++)
    {
        Top(ss,e);
        Pop(ss); 
        printf("%d ", e); 
    } 
    printf("\n"); 
    system("pause"); 
}
