What will be the output of this C program

Question

What will be the output of following programs :

void fun1(struct node* head)

 {

    for(head == NULL)
    {
        return;
    }

    fun1(head->next);

    printf("%d  ", head->data);
 }

 And this one !

 

void fun1(struct node* head)

 {

    while(head == NULL)
    {
        return;
    }

    fun1(head->next);

    printf("%d  ", head->data);
 }
