Inserting an element into Linked List in C Programming Language

#include<stdlib.h>
typedef struct Node
{
        int data;
        struct Node *next;
}node;


void insert(node *pointer, int data)
{
       while(pointer->next!=NULL)
        {
                pointer = pointer -> next;
        }
        pointer->next = (node *)malloc(sizeof(node));
        pointer = pointer->next;
        pointer->data = data;
        pointer->next = NULL;
}

//Printing the elements in linkedlist.
void print(node *pointer)
{
        if(pointer==NULL)
        {
                return;
        }
        printf("%d ",pointer->data);
        print(pointer->next);
}

int main()
{
        node *start,*temp;
        start = (node *)malloc(sizeof(node));
        temp = start;
        temp -> next = NULL;

         // Inserting elements into linked List
          insert(start,2);
