Core Java · interview question
Why does a cart program need a loop when calculating a subtotal for many items?
Multiple choiceMediumchapter-1-curatedpremiumcore-javaloops-and-iteration
Answer and explanation
Correct answer
C. Because the same calculation must be repeated across a changing set of cart lines
Why
A cart can hold more than one item, so subtotal logic must repeat per line. Loops are the basic tool for applying the same step to each element in a collection or sequence.
