LinkedList Struct Typedef in C

Question

I am try to build a basic linked list in C. I seem to get an error for this code:

typedef struct
{
    char letter;
    int number;
    list_t *next;
}list_t         


        

Answer 1

When you are using list_t *next in your code, the compiler doesn't know what to do with list_t, as you haven't declared it yet. Try this:

typedef struct list {
    char letter;
    int number;
    struct list *next;
} list;

As H2CO3 pointed out in the comments, using _t as an identifier suffix is not a great idea, so don't use list_t.
