^^^^^^^^^^^^
Also this line is going to cause error.

int NUM;
cin>>NUM;
node *ARR[NUM];

struct node *ptr[10]; /* 10-element array of pointers */

Huh? That's C++, not C.

node *ARR[NUM];

No, if you want to allocate at runtime, you do this:

VLA is legal in C99, isn't it?

Sorry, that should be:

typedef struct node_ node;

to add some small confusion, can't you also do this?

struct node_;
typedef struct node_ node;

struct node_
{
int data;
node *ptr;
}

or...
typedef struct node_
{
int data;
struct node_ *ptr;
}


many ways... one cat.

Everyone has a preference on which is more readable. As a friend of mine put
it, "Programming is as much a science about computers as it is about the
psychology of the programmers"
