Understanding Data Structures

What are primitive data types?

• Primitive data types are basic data types like integers, floats, characters, and booleans.

• Primitive data types include lists and dictionaries.

• Primitive data types are complex data structures.

• Primitive data types are only used in object-oriented programming.

Choose three examples of primitive data types.

• float

• integer

• boolean

• String

What is a reference variable?

• A reference variable is a type of function.

• A reference variable is an alias for another variable, allowing direct access to its value.

• A reference variable is a data structure that holds multiple values.

• A reference variable is a constant value that cannot change.

How does a reference variable differ from a primitive variable?

• Both reference and primitive variables hold direct values.

• A reference variable points to an object, while a primitive variable holds a direct value.

• A reference variable holds a direct value, while a primitive variable points to an object.

• A reference variable is a type of primitive variable.

Explain the concept of memory allocation for primitive data types.

• Memory allocation is only necessary for complex data types.

• Memory allocation involves reserving a specific amount of memory based on the type.

• Memory allocation for primitive data types is irrelevant to programming.

• Primitive data types do not require any memory allocation.

What is the significance of using reference variables in data structures?

• Reference variables increase data redundancy in structures.

• Reference variables are significant in data structures for efficient memory management and direct data manipulation.

• Reference variables are primarily for user interface design.

• Reference variables are only used for string manipulation.

Can a reference variable point to multiple objects? Why or why not?

• A reference variable can hold a list of objects at once.

• No, a reference variable cannot point to multiple objects at the same time.

• A reference variable can point to one object and switch to another later.

• Yes, a reference variable can point to multiple objects simultaneously.

What happens when a reference variable is assigned to another reference variable?

• The original object is deleted from memory.

• Both reference variables create a new object in memory.

• One reference variable becomes null after assignment.

• Both reference variables refer to the same object in memory.
