Trying to create a linked list but error with pointer assignment

Question

I am trying to make a linked list and create some methods. However, I am getting the error:

Assignment makes pointer from integer without a cast.

Answer 1

If the error is on the commented line, then maybe ID is a pointer, not an int. This will work fine:

students->ID = 0; 

because it sets the pointer to NULL, so it compiles without error/warning.
