如何在c中删除链表中的表头？

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

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

// 删除链表的表头
void deleteHead(struct Node** head) {
    if (*head == NULL) {
        return;
    }
    
    struct Node* temp = (*head)->next;
    free(*head);
    *head = temp;
}

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

int main() {
    // 创建链表
    struct Node* head = (struct Node*)malloc(sizeof(struct Node));
    struct Node* second = (struct Node*)malloc(sizeof(struct Node));
    struct Node* third = (struct Node*)malloc(sizeof(struct Node));
    
    head->data = 1;
    head->next = second;
    
    second->data = 2;
    second->next = third;
    
    third->data = 3;
    third->next = NULL;
    
    printf("链表删除前：");
    printList(head);
    
    // 删除表头
    deleteHead(&head);
    
    printf("链表删除后：");
    printList(head);
    
    return 0;
}
