A2 13.1 L1 User defined data types

What is a composite data type?

• A pointer that references a memory location
• An enumerated type
• A data type made up of multiple base data types
• A data type that only stores one base type

Which of the following best describes a non-composite data type?

• A data type made of a single base type
• An ordered list of allowed values
• A type that mixes pointers and arrays
• A data type composed of different base types

What is an enumerated (enum) type?

• A dynamic data structure
• A list of allowed values for a variable
• A data structure that stores pointers
• A composite type structure

Why must enumerated values in an enum not be enclosed in quotes in pseudocode?

• They would be treated as string literals
• Quotes cause syntax errors
• They are reserved keywords
• They represent numerical ordinals with an implied order

What is the primary purpose of using enumerated data types?

• To restrict a variable to a set of predefined, ordered values
• To allow any arbitrary value
• To combine multiple data types
• To handle dynamic memory allocation

What is the main function of a pointer data type?

• To store multiple data types
• To create composite structures
• To list enumerated values
• To reference a memory location for dynamic data structures

Which data structure typically uses pointers for dynamic behavior?

• Static arrays
• Composite records
• Linked lists and stacks
• Enumerated lists

When declaring a pointer in pseudocode what special symbol is used?

• A pointer symbol (hat symbol)
• An ampersand (&) symbol
• An asterisk (*) symbol
• An at sign (@)

What does dereferencing a pointer in pseudocode mean?

• Changing the pointer's memory address
• Declaring a new pointer
• Accessing the value at the referenced memory location
• Initializing a pointer variable

A pointer data type is classified as which kind of user defined type?

• Composite
• Non-composite
• Aggregated
• Enumerated
