Lists are used to store all input data so that there is a running record of all user input.

Answer 1

The benefits of using a list as a data abstraction in a program include easy size updates, prevention of duplicate values, and flexible data storage.

Therefore, the correct answer is: option 'Lists often allow their size to be easily updated to hold as many data values as needed.

Step-by-step explanation:

Data abstraction is the reduction of a particular body of data to a simplified representation of the whole. One benefit of using a list as a data abstraction in a program is that it often allows easy updating of its size to hold as many data values as needed.

This means that you can add or remove elements from the list as required, without having to worry about fixed sizes or constraints.

Another benefit is that lists prevent duplicate data values from appearing in the list. This ensures that each value in the list is distinct, making it useful for scenarios where uniqueness is important, such as storing a list of unique usernames.

Lastly, lists are not converted to strings by default. They can hold a variety of data types, including integers, floats, strings, etc., without any conversion. This allows for efficient and flexible storage of different types of data in a program.
