Based on the coverage so far in the lectures, we have to limit ourselves to four attributes: “id”, “year”, “price”, and “quanity” for all products in this assignment, where we only keep the “year” component of a “date” for time representation. More specifically, we use separate integer arrays to store “id” values, “year” values, and “quantity” values, respectively, but for “price” values, we need a float array to preserve the precision. Since arrays are static structures, we also need to specify the maximum size “MAX_LENGTH”, which should be defined as a constant such as 100. In addition, the access to these arrays should be synced since the corresponding elements with the same index are the different attributes of the same product
