c - c中链表的反向打印

Question

我正在尝试打印反向链表。但我只得到一个值。我哪里错了？请耐心等待，因为我是 C 语言的新手。

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

struct itemlist {
    int value;
    struct itemlist *next;
};

typedef struct itemlist item;

int main(void) {
    itemlist *curr,*head,*tail;

    head=NULL;
    tail=NULL;

    for (int i = 1; i < 10; i++) {
        curr=(itemlist *)malloc(sizeof(itemlist));
        curr->value=i;
        curr->next=tail;
        tail=curr;
        if (!head)
            head=curr;
    }

    curr=head;

    while (curr) {
        printf("Curr value is:%d\n",curr->value);
        curr=curr->next;
    }

    return 0;
}

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

struct itemlist
{
        int value;
        struct itemlist *next;
};

typedef struct itemlist item;

int main(void)
{
        itemlist *curr,*head,*prev;

        head=NULL;
        curr=NULL;
        prev=NULL;

        for(int i=1;i<10;i++)
        {
                curr = new itemlist;
                curr->value = i;
                curr->next = NULL;

                if (head == NULL)
                   head = curr;
                if(prev != NULL)
                   prev->next = curr;

                prev = curr;
        }

        curr=head;

        while(curr)
        {
                printf("Curr value is:%d\n",curr->value);
                curr=curr->next;
        }
        return 0;
