Which of the following is NOT a characteristic of a List?

• A. A collection of data items
• B. Uses identifiers to access items
• C. Can only contain integers
• D. Items are ordered

Answer: (C)

A List is a fundamental data structure used in programming and computer science, characterized by several key properties. One of its defining features is that it serves as a collection of data items. This means it can hold multiple values, which can be of various data types like strings, integers, objects, and more, rather than being restricted to just integers. Another characteristic of a List is that items are accessed using identifiers, often referred to as indices or keys. This allows for efficient retrieval and modification of items within the list, as each item can be uniquely identified based on its position. Additionally, Lists maintain an order in which items are stored and accessed. This property is essential for many applications, as it enables predictable data manipulation and retrieval sequences. Therefore, while the first, second, and fourth options are accurate traits of Lists, the assertion that a List can only contain integers is not true. Lists can hold various types of data, making them versatile and widely used in programming and data management tasks.
