Multiple choiceHardchapter-2-curatedpremiumoopclasses-and-objects
Answer and explanation
Correct answer
C. Use a static variable to count the number of objects and assign it as an ID
Why
Using a static variable to count the number of objects ensures that each 'Product' object gets a unique identifier. Static variables are shared across all instances, so they can be incremented with each new object creation.
