When should I use stack vs heap in C++?

Can you explain when to use stack vs heap in C++?

Sure! In C++, stack memory is used for static memory allocation, while heap memory is used for dynamic memory allocation.

What are the advantages of using stack memory?

Stack memory is faster to allocate and deallocate, and it automatically cleans up when the function exits.

And what about heap memory?

Heap memory allows for dynamic allocation, meaning you can allocate memory at runtime, but you must manage it manually.

Are there any downsides to using heap memory?

Yes, heap memory can lead to fragmentation and memory leaks if not managed properly.

So, when should I choose one over the other?

Use stack for small, fixed-size data and when you need speed. Use heap for large or variable-sized data that needs to persist.
