Which statement is true regarding Lists and Arrays?

• A. Array elements can be modified only
• B. Only Lists can be iterated using a For Each loop
• C. Both Array and List elements can be accessed by index
• D. Lists cannot have items added once created

Answer: (C)

The statement regarding Lists and Arrays that is true is that both Array and List elements can be accessed by index. This means that in both data structures, you can retrieve or modify the elements by specifying their position within the collection. In programming, arrays are typically fixed-size collections where each element is accessed via its index, starting from zero. Similarly, lists are often dynamic collections that also allow for indexed access to their elements. The ability to use an index to directly access data is essential for efficient data manipulation and retrieval in both structures. For the other statements, arrays are indeed modifiable, so the assertion that they can be modified only isn’t accurate. Regarding iteration, both Arrays and Lists can be iterated using a For Each loop, not only Lists. Lastly, lists are inherently designed to allow addition of items after they have been created, contradicting the notion that they cannot have items added once initialized. Thus, the correct understanding of indexed access in both data structures underlines the truth of the chosen statement.
