If you are defining node in a linked list , then you can do it using structure.

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

If you want to store multiple information in a node then you can do it like this

struct node {
   int num1;
   int num2;
   char ch1;
   char ch2;
};
3

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

OR in a single statement

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