这种体型怎么写 有点想不出来了

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

struct node
{
    int num;
    struct node *next;
};

struct node *createReverseList()
{
    int x;
    struct node *head = NULL;
    while (1)
    {
        scanf("%d", &x);
        if (x == 0)
            return head;
        struct node *p = (struct node *)malloc(sizeof(struct node));
        p->next = head;
        p->num = x;
        head = p;
    }
}

void printList(struct node *head)
{
    struct node *p = head;
    while (p)
    {
        printf("%d ", p->num);
        p = p->next;
    }
    printf("\n");
}

void deleteList(struct node *head)
{
    struct node *p = head;
    while (p)
    {
        struct node *q = p;
        p = p->next;
        free(q);
    }
}

int main()
{
    struct node *list = createReverseList();
    printList(list);
    deleteList(list);
    return 0;
}
