Abstract Data Types

What is the difference between data types and abstract data types?

• Data types define a certain domain of values, while abstract data types define operations allowed on those values.
• Data types define operations allowed on values, while abstract data types define a certain domain of values.
• Data types and abstract data types are the same thing.
• Data types and abstract data types are not related.

Which of the following is an example of a user-defined data type?

• Integer
• Character
• Float
• Structure

What is the purpose of abstract data types?

• To provide abstraction and hide implementation details from the user.
• To define a certain domain of values.
• To perform operations on data types.
• To implement data structures.

How are abstract data types implemented?

• Using arrays or linked lists.
• Using primitive data types.
• Using user-defined data types.
• Using mathematical operations.

What is the advantage of using abstract data types?

• It allows the user to use operations without knowing the implementation details.
• It allows the user to define a certain domain of values.
• It allows the user to implement data structures.
• It allows the user to perform mathematical operations.

What is a client program?

• A program that uses data structures.
• A program that implements data structures.
• A program that defines abstract data types.
• A program that performs mathematical operations.

How does abstract data type provide abstraction?

• By hiding implementation details from the user.
• By defining a certain domain of values.
• By performing operations on data types.
• By implementing data structures.

What happens if the implementation of an abstract data type is changed?

• The client program remains unaffected.
• The client program needs to be rewritten.
• The client program stops working.
• The client program becomes more efficient.

What is the purpose of using abstract data types?

• To separate the interface from the implementation.
• To define a certain domain of values.
• To perform operations on data types.
• To implement data structures.

Which of the following is an example of an abstract data type?

• Integer
• Character
• Float
• Stack
