How to Create Linked List in C/C++

Here is the Code to create linked list

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

struct Node{
    int data;
    struct Node *next;
 };
 
typedef struct Node *node;

node createNewNode(){
    node temp; 
    temp = (node)malloc(sizeof(struct Node)); // allocate memory equal memory as the size using malloc()
    temp->next = NULL;// make next point to NULL (suppose this as last node)
    return temp;
}

node addNode(node head, int value){
    node tmp,p;
    tmp = createNewNode();
    tmp->data = value;
    if(head == NULL){
        head = tmp;
    }
    else{
        p  = head;
        while(p->next != NULL){
            p = p->next;
        }
        p->next = tmp;
    }
    return head;
}

int main()
{
    node head = NULL;
    head = addNode(head,2);
    head = addNode(head,3);
    head = addNode(head,5);
    head = addNode(head,8);
    node p;
    p = head;
    while(p != NULL){
        printf("%d\n",p->data);
        p = p->next;
    }
    
    return 0;
}
