Which data structure stores multiple values of the same type?

Which data structure stores multiple values of the same type?

• A. Arrays
• B. Objects
• C. Attributes
• D. Functions

Answer: (A)

The main idea is a structure designed to hold several items in one variable, with uniform type and index-based access. An array is built for that purpose: it is an ordered collection where each element has a position, and all elements are of the same type (or treated as such in practice). This makes it easy to loop through values, access a specific item by its index, and perform bulk operations on the entire set. Objects, on the other hand, group data as named fields, which can be of different types, and are accessed by keys rather than by a numeric index. Attributes are metadata about data rather than a container for multiple values. Functions are blocks of executable code, not collections of values. So the data structure that stores multiple values of the same type is an array.
