Stack vs. Heap

Stack vs. Heap

In this lesson — part of Memory Model — you'll learn stack vs. heap in C++ and why it matters in real work.

Why it matters

Understanding memory — allocation, references, leaks — is essential for fast, correct systems code.

Key ideas

• Stack vs. heap
• Allocation and deallocation
• References and ownership
• Leaks and how to avoid them

In practice

Here's the idea in pseudocode — the exact syntax varies by language:

// C++: allocate and free
buf = alloc(1024); ... free(buf)

Try it yourself

Exercise: In C++, demonstrate the difference between stack and heap allocation.

Recap

You now understand stack vs. heap and can apply it in C++. Mark this lesson complete and continue to the next one.
