}

this is partial of the project:
1) Create a CD_type_node structure having the following fields:
CD number
CD title
CD count
A pointer to CD_type_node to point to next CD.

2) Create a Artist_type_node structure having the following fields:
Artist’s name
A pointer to a CD_type_node, to enable you to create a linked list for CDs.

3) In your main, create an array of type Artist_type_nodes that can store up to 100 elements.

Thus, your database will be an array of 100 Artists, where each Artist has a list of CDs. Basically, each Artist’s name and a pointer to the list of CD’s will be stored in the Artist_Array.

when i compile this is what it tells me: struct CD_type_node has no element Artist_name

how do i make the correct linked list and how do i create the array

Where is Artist_name defined? Is it in CD_type_node?

no its created as a separate linked list node, atleast that's how i understand it, i do not know if its right.. because the assignment says create a CD_type_node and create Artist_type node with a pointer to CD_type_node. i dont know if its a struct within a struct because that didnt work as well

A struct within a struct is not a pointer to a struct. See my emphasis in your post...

You need a field, like next, that points to a CD Node. The address of the proper CD Node goes into this pointer in the Artist Node.

int main()
{
    struct Artist_type_node artists[100];
    // extra code here
    mylist = insert(mylist, struct Artist_type_node *artists);

}

thats what i changed, the problem is, it wont let me pass the struct as an argument to a function. isnt that the correct syntax for sending a struct to a function

mylist = insert(mylist, struct Artist_type_node *artists);

Did you try

mylist = insert(mylist, *artists);
