Memory: stack, heap, scope, and lifetime.

In this walkthrough, we connect core concepts from stack vs heap, scope vs lifetime, and uninitialized state into one unified mental model: memory is real, names are not. You’ll learn why values always live somewhere, why scope doesn’t guarantee destruction, and why memory doesn’t reset itself between executions. If you’ve ever experienced “random” bugs, stale state, or disappearing values, this video explains why they weren’t random at all. Think in memory. Think in time. #ProgrammingFundamentals #MemoryModel #StackVsHeap #ExecutionThinking #SoftwareEngineering
