Why append function is not working?

Question

#include <stdio.h>
#include <stdlib.h>
//Compiler version gcc 6.3.0
struct Node
{
int data;
struct Node* link;
};

struct Node* head=NULL;
struct Node* tail=NULL;

void append(int x)
{
struct Node* temp=(struct Node*)malloc(sizeof(struct Node));
temp->data=x;
temp->link=NULL;
if(tail!=NULL)
tail->link=temp;
tail=temp;
}

int main(void)
{
head=tail;
int n;
scanf("%d",&n);
int x;
for(int i=0;i<n;i++)
{
scanf("%d",&x);
append(x);
}
struct Node* temp=head;
while((*temp).link!=NULL)
{
printf("%d\n",(*temp).data);
temp=(*temp).link;
}
printf("%d",(*temp).data);
}
