(a) array

(b) queue

(c) stack

(d) heap

This question was posed to me during an internship interview.

My enquiry is from Buffer Overflow in section Cyber Security of Cyber Security

Answer 1

Correct choice is (d) heap

To explain I would say: Variables that gets created dynamically when a function (such as malloc()) is called is created in the form of heap data-structure. In heap-based overflow, the buffer is placed on the lower part of the heap, overwriting all dynamically generated variables.
