如何在C中创建一个空的链表？

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

struct Node* head = NULL;

struct Node* newNode = (struct Node*)malloc(sizeof(struct Node));

newNode->data = value;
newNode->next = NULL;

if (head == NULL) {
    head = newNode;
}
else {
    struct Node* temp = head;
    while (temp->next != NULL) {
        temp = temp->next;
    }
    temp->next = newNode;
}

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

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

void printList(struct Node* head) {
    struct Node* temp = head;
    while (temp != NULL) {
        printf("%d ", temp->data);
        temp = temp->next;
    }
    printf("\n");
}

int main() {
    struct Node* head = NULL;
    int i;

    for (i = 1; i <= 5; i++) {
        struct Node* newNode = (struct Node*)malloc(sizeof(struct Node));
        newNode->data = i;
        newNode->next = NULL;

        if (head == NULL) {
            head = newNode;
        }
        else {
            struct Node* temp = head;
            while (temp->next != NULL) {
                temp = temp->next;
            }
            temp->next = newNode;
        }
    }

    printf("Linked List: ");
    printList(head);

    return 0;
}
