1// Typedefs can also simplify definitions or declarations for structure pointer types. Consider this:
2
3struct Node {
4    int data;
5    struct Node *nextptr;
6};
7// Using typedef, the above code can be rewritten like this:
8
9typedef struct Node Node;
10
11struct Node {
12    int data;
13    Node *nextptr;
14};
