Incompatible type for argument and uninitialised in this function

Question

I am having an issue with one/two of my methods when I am calling it in main() and I\'m unsure why.

int main()
{
    struct list * list;

    lis         


        

Answer 1

Issue:1: Change the return type of list_init

struct list* list_init()
{
    list = malloc(sizeof(*list));
    if(list != NULL)
    {
        list->head = NULL;
        list->num_books = 0;
    }
    return list;
}

And call it this way in main()

int main() {

    struct list * list;

    list = list_init();

Issue:2:

After this another issue is that in while loop every time you are taking local copy of book and using that pointer in list_add()

    struct book book1;

I suggest to malloc every time, SO for every entry you will have seperate copy of book
