Compare heap and stack memory

Q: Compare heap and stack memory

This question evaluates understanding of memory management concepts including stack versus heap allocation, object lifetimes, allocation and free behavior, access patterns, performance characteristics, and thread visibility within the Coding & Algorithms domain.

Q: How do I approach Coding & Algorithms interview questions?

Coding & Algorithms questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master coding & algorithms interviews.

Question

Compare heap and stack memory. Explain how each is allocated and freed, typical lifetimes of data stored there, access patterns and performance characteristics (allocation cost, locality, cache behavior), thread visibility (thread-local stacks vs shared heap), and common pitfalls such as stack overflow, heap fragmentation, and escaping references. Provide examples of when you would prefer one over the other and discuss how recursion depth and large objects affect the choice.
