Only provide the necessary codes based on the instructions of each question. DO NOT provide additional or more codes for each question, or points will be deducted for unrelated codes in each question. Question A instruction: Under the comment block a, declare instance variables to record product attributes, including product ID, product name, unit cost, unit price, quantity on hand, and status.
