Answer:
The statements which are true are;
- A user-defined data type can include other user-defined data types
- A user-defined data type is defined using a class
- A user-defined data type can include a list
Explanation:
A user-defined data type (UDT) is a datatype that is defined and derived by the use of the datatypes which preexist including existing user-defined datatypes and the built-in datatypes
It is therefore true that a user-defined data type can include other user-defined data types
A class is a user-defined data type that contains both its member data and member functions, that can be used when an instance of the class is first created
Therefore, a user-defined data type is defined using a class
In a user-defined data type, a variable has actual data within it which can include an array or list
Therefore a user-defined data type can include a list.
