💡 TL;DR：Read STL implementation guides in a deliberate order: sequence containers, tree and hash containers, iterators, invalidation and type traits.

Source-Code Analysis · Article Index

These articles explain implementation choices, not just the public STL API. Some source listings come from older GCC releases; check the version named in an article before applying an internal detail to a current standard library.

Choose a source-code path

1. Sequence containers: begin with array, then compare vector and deque storage and iterator behavior.
2. Associative containers: study the red-black tree before map and multimap; compare that with unordered_map and its hash-table structure.
3. Correctness: connect iterator internals with the iterator invalidation guide so performance changes do not introduce dangling iterators.
4. Template machinery: use the traits guide when an implementation relies on type extraction.
