    typedef confusion (LINKED LIST)

    Part of a code in the book has whats below. They've said that typedef node *list
    and then went onto say that list head.
    So what actually is head now? Is it a structure?


    Code:
    typedef struct node_type
    {
    char data;
    struct node_type *next;
    }node;
    
    typedef node *list;
    list head;

    A typedef creates an alias of sorts. In your case, node is an alias for struct node_type and list is an alias for node* which is actually then struct node_type*.

    So... head is a struct node_type pointer.

Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."
