Which statement is true? Select 3 options.
irina1246 [14]

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.
