Understanding Non-Composite Data Types

What is a user-defined data type?

• A data type that is built into the programming language.

• A data type based on an existing data type or other data types defined by a programmer.

• A data type that does not reference any other data types.

• A data type that uses the memory address of where the data is stored.

Which of the following is a non-composite data type?

• Array

• Structure

• Pointer

• Class

What is an enumerated data type?

• A data type that uses the memory address of where the data is stored.

• A non-composite data type defined by a given list of all possible values that has an implied order.

• A data type that references other data types.

• A data type that can use set theory operations such as intersection and union.

Which of the following best describes a pointer data type?

• A data type that contains a list of items.

• A data type that does not reference any other data types.

• A data type that uses the memory address of where the data is stored.

• A data type that can be defined without referencing another data type.

What is a set in the context of data types?

• A data type that contains a list of items in a specific order.

• A given list of unordered elements that can use set theory operations such as intersection and union.

• A data type that uses the memory address of where the data is stored.

• A data type that references other data types.

Which of the following is true about non-composite data types?

• They can reference other data types.

• They are always primitive types available in a programming language.

• They can be defined without referencing another data type.

• They are always user-defined data types.

Enumerated data types are usually used for:

• Storing memory addresses.

• Lists of items.

• Performing set theory operations.

• Referencing other data types.

Which of the following is NOT a characteristic of a non-composite data type?

• It does not reference any other data types.

• It can be a primitive type available in a programming language.

• It can be a user-defined data type.

• It must reference at least one other data type.

What is the primary use of a pointer data type?

• To store a list of items.

• To define a set of unordered elements.

• To use the memory address of where the data is stored.

• To define a list of all possible values with an implied order.

Which of the following operations can be performed on a set?

• Memory allocation

• Intersection and union

• Defining a list of items

• Referencing other data types
