How to Create Linked List in C/C++

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

    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){
