数据结构的基本代码C语言

数据结构的基本代码C语言包括头文件和结构体定义等内容，以下是一个简单的链表的代码示例：

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

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

Node *createNode(int data) {
    Node *newNode = (Node*)malloc(sizeof(Node));
    newNode->data = data;
    newNode->next = NULL;
    return newNode;
}

void insertAtEnd(Node **headRef, int data) {
    Node *newNode = createNode(data);
    if (*headRef == NULL) {
        *headRef = newNode;
        return;
    }
    Node *current = *headRef;
    while (current->next != NULL) {
        current = current->next;
    }
    current->next = newNode;
}

void traverseList(Node *head) {
    if (head == NULL) {
        printf("List is empty!\n");
        return;
    }
    Node *current = head;
    while (current != NULL) {
        printf("%d ", current->data);
        current = current->next;
    }
}

int main() {
    Node *head = NULL;
    insertAtEnd(&head, 10);
    insertAtEnd(&head, 20);
    insertAtEnd(&head, 30);
    traverseList(head);
    return 0;
}

以上代码实现了一个简单的链表，包括节点的创建、节点的插入以及遍历等操作。
