STL Containers, Ranges, Views, and Zero-Copy Spans
Dissect container memory layouts (vector vs deque vs node-based lists), hash table bucket dynamics, iterator invalidation hazards, C++20 Ranges, and non-owning std::span.
Templates and container interfaces
Deep knowledge of vector, deque, and hash map memory layouts, iterator invalidation rules, and non-owning std::span.

- 07.01Sequence Containers: Memory Layout of vector, deque, and list4 min
Analyze the low-level physical memory layout and performance trade-offs of std::vector (geometric growth), std::deque (chunked paging), and std::list (node pointer chasing).
- 07.02Associative Containers: std::map vs std::unordered_map Mechanics4 min
Compare Red-Black tree ordered maps (std::map) with hash-table bucket maps (std::unordered_map): load factors, hash collisions, rehashing, and Robin Hood hashing alternatives.
- 07.03Iterator Invalidation Hazards and Safe Container Mutation4 min
Master iterator invalidation rules across standard containers: vector reallocation traps, safe erasure patterns, and avoiding dangling pointer corruption.
- 07.04Modern Non-Owning Views: C++20 Ranges and std::span4 min
Eliminate defensive copying and buffer decay using modern zero-copy primitives: non-owning contiguous std::span, C++20 Ranges, lazy pipeline views, and pipe operators (|).
Ready to move on?
Construct lazy C++20 Ranges pipelines and pass contiguous buffers via std::span.
