All are user-defined datatypes which allow the user to create their own datatype which can be a combination of int, float, char, etc.

@Kamal.

Linked list: list is a collection of elements. There are 2 ways of maintaining list in computer memory. The first way is to take an array for sorting elements of the list. But arrays have some disadvantage. Insertion and deletion of the element require more processing. The second way is implementing a list in a memory by using a self-referential structure.

Structure mean collection of multiple element that can be of different data types. Definition of union is same of structure but only data element is stored in union variable.

Because the secondary data types are arrays, pointers, structures, union and enum, they are user defined data types All of them let you define new data types.

I can't understand explain clearly.

Structure are user define data types in which you can store more than one data type variable. It is similar to union. But in union you can access only one value at a time because in union memory allocated to only one member at a time. While in structure all of its member have its own memory. That's why structure is taking more memory then union.
