Which of the following is false?

Question

A. A stack automatically deallocates space when variables are no longer needed.
B. A heap must be manually managed.
C. A heap is generally faster than a stack.
D. A stack uses a last in, first out (LIFO) approach.

Answer 1

The false statement among the options is:

C. A heap is generally faster than a stack.

In general, stack memory allocation and deallocation are much faster than heap memory operations due to the way they are managed. Stack memory is managed through simple pointer adjustments, while heap memory management involves more complex operations for allocation and deallocation, which can introduce overhead.
