You're working on a C program that needs to manipulate and process data about a list of products in a store. Each product has several attributes like name, price, and quantity. What approach would you take to store and process this data efficiently?

An array of structures would be an efficient approach for storing and processing data about products in a store. This data structure allows you to create a custom data type that contains all the attributes of each product (name, price, quantity), making it easy to manage and process product information efficiently.
