How to return pointer adress for structure variable

I was working on data structures and while I was writing some code, I needed to return the address of the pointer that was defined in the structure. So here’s my code but when I compile and run it, it doesn’t work and give an error message as " assignment makes pointer from integer without a cast ". How should I rewrite it?

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct Node{
    
    int x;
    struct Node *next;
    
};


void main(){
    int i;
    struct Node *head;
    head = (struct Node*) malloc(sizeof(struct Node));
    head->next=NULL;
    
    
    /*Ekle(5,head);
    Ekle(10,head);
    Ekle(15,head);
    printf("Enter the value of 'ara' element");
    scanf("%d",&i);
    Print(head);
    ArayaEkle(i,20,head);
    Print(head);*/
    
    head = siraliEkle(10,head);
    head = siraliEkle(5,head);
    Print(head);
    
}

void Print(struct Node *root){
    
    while(root->next!=NULL){
        root = root->next;
        printf("%dn",root->x);
        
        
    }
}

struct Node *siraliEkle(int sayi, struct Node *root){
    
    if(root==NULL){
        root = (struct Node*) malloc(sizeof(struct Node));
        root->x = sayi;
        root->next = NULL;
        return root;
    }
    
    else if(root->next==NULL){
        if(root->x>sayi){
            struct Node *temp = (struct Node*) malloc(sizeof(struct Node));
            temp->x = sayi;
            temp->next = root;
            root = temp;
            return root;
        }
    }
    
    
}
