Allocation decisions

What this memory-allocation operating systems question tests

This is an easy multiple-choice question that probes your understanding of how dynamic memory allocation works in C++. It asks you to reason about the behaviour and correctness of allocation patterns—a foundational skill for systems programming and interview readiness.

Questions in this category reward close reading of code and a mental model of the heap, pointers, and allocation semantics. You'll need to distinguish between valid and invalid memory-management practices, and understand the consequences of different allocation strategies. This is the kind of question that tests whether you've internalised the basics before moving on to more complex concurrency or performance scenarios.
