Why use an asterisk after a type?

+3
−0 
#include<stdio.h>
struct Node{
     int data;
     struct Node* next;
};

Here I used an asterisk after Node. What is it used for? What if I don't put any asterisk after Node (both Node's are structures)?

Is *ptr and ptr* same?

It's a pointer. I don't have enough time to write a full answer right now, but here's a starting point.

Monica Cellio‭ Is *ptr = ptr* ? In my code I had wrote Node*. In this link, they had gave example of *ptr.

deleted user Depends on the context. During declaration of the variable, you can write Node* ptr, Node *ptr or Node * ptr, it's a matter of style. (the former 2 styles are most common). When de-referencing the pointer to get the items it points at, you always write *ptr.
