程式碼非常簡單，直接程式碼stackg.h

 1 #ifndef stackg_h
 2 #define stackg_h
 3 
 4 #include <stdio.h>
 5 #include <stdlib.h>
 6 
 7 typedef int DataType;
 8 
 9 typedef struct node_{
10     DataType data;
11     struct node_ *next;
12 } Node;
13 
14 typedef struct list_{
15     Node *head;
16     Node *tail;
 
17     Node *current;
18 } List;
19 
20 void initList(List *);
21 void push(List *, DataType);
22 void pop(List *);
23 Node *getTop(List *);
24 int getLength(List *);
25 void dispList(List *);
26 
27 #endif

對應的實現檔案stackg.c

 1 #include "stackg.h"
 2 
 3 void initList(List *list){
 4     list->head = NULL;
 
 5     list->tail = NULL;
 6     list->current = NULL;
 7 
 8     return;
 9 }
10 
11 void push(List *list, DataType data){
12     //1、建立一個節點
13     Node *node = (Node *)malloc(sizeof(Node));
14     node->data = data;
15     node->next = NULL;
16 
17     //2、插入節點準備
18     if(list->head == NULL){
 
19         list->tail = node;
20     }else{
21         node->next = list->head;
22     //3、插入節點
23     }
24     list->head = node;
25 
26     return;
27 }
28 
29 void pop(List *list){
30     list->head = list->head->next;
31 
32     return;
33 }
34 
35 Node *getTop(List *list){
36     Node *node = (Node *)malloc(sizeof(Node));
37     node = list->head;
38 
39     return node;;
40 }
41 
42 int getLength(List *list){
43     Node *node = (Node*)malloc(sizeof(Node));
44     node = list->head;
45     int i = 0;
46     while(node != NULL){
47         node = node->next;
48         i++;
49     }
50 
51     return i;
52 }
53 
54 void dispList(List *list){
55     Node *node = (Node *)malloc(sizeof(Node));
56     node = list->head;
57     int i = 0;
58     while(node != NULL){
59         printf("the %dth node: %d\n", i + 1, node->data);
60         node = node->next;
61         i++;
62     }
63     printf("display finished\n");
64 
65     return;
66 }

測試檔案testStackg.c

 1 #include "stackg.h"
 2 
 3 int main(int argc, char **argv)
 4 {
 5     List *list = (List *)malloc(sizeof(List));
 6     initList(list);
 7     push(list, 4);
 8     push(list, 6);
 9     push(list, 8);
10     push(list, 10);
11     dispList(list);
12     Node *tmp = getTop(list);
13     printf("getTop result: %d\n", tmp->data);
14     pop(list);
15     dispList(list);
16     pop(list);
17     dispList(list);
18     printf("the list: %d\n", getLength(list));
19 
20     return 0;
21 }

直接執行即可，win10下linux子系統ubuntu18.04
