Chapter Assessment
You have reached the end of the Array chapter. This checkpoint tests what you can apply, not what you can recite: the memory layout behind index access, the cost of each operation, how the six languages differ, and the reasoning behind the four problems you solved. The pool holds 24 questions and serves 12 per attempt, mixed across easy, medium, and hard. Use the hint if you get stuck, and read the explanation on every option, including the ones you did not pick.
