let say for a course structure:

Major : SubjectA -> SubjectB
core : SubjectC -> SubjectD
Elective: SubjectE

I'm familiar with linked lists, but I'm not entirely sure what you're asking for? Could you elaborate, please? By adjacency list, are you implying that you want to create a list of all of the links in the linked list? If so, then wouldn't that defeat the purpose of using a linked list? Or am I misunderstanding what you're asking for?

An adjacency list is a list of lists. It's just like a list, but instead of having data in the node, you have a pointer to another list. Using your example, your main list would be MajorList->CoreList->ElectiveList. You traverse this list to get a particular group of courses. Then you would traverse that resulting list to get a particular course in that group.

| | |
SubjectA SubjectC SubjectE
| |
SubjectB SubjectD
|
NULL

Is it possible to use struct within a struct to do it?

MajorList -> SubjectA -> SubjectB
|
CoreList -> SubjectC -> SubjectD
|
ElectiveList -> SubjectE
