In modern C++, choosing the right associative container can be complex. It’s essential to understand their characteristics, such as maps and sets, to optimize performance and suitability for specific applications.
Associative containers can be categorized into types like maps and sets, where maps store key-value pairs while sets only contain keys. The choice of structure directly influences performance.
Ordering is another aspect to consider; ordered containers maintain a consistent key arrangement, while unordered containers do not, which affects operations like search and insertion.
Understanding the internal structure is crucial: node-based containers offer stable references but may be less efficient than flat containers, affecting overall performance and memory usage.
