What are some alternatives to std::map in C++17?

What are some alternatives to std::map in C++17?

In C++17, you can consider using std::unordered_map for faster lookups, or std::vector with std::pair for ordered data.

What are the advantages of using std::unordered_map?

std::unordered_map offers average constant time complexity for lookups, insertions, and deletions, making it efficient for large datasets.

Are there any downsides to using std::unordered_map?

Yes, std::unordered_map uses more memory due to its hash table implementation, and performance can degrade with poor hash functions.

When should I prefer std::map over std::unordered_map?

You should prefer std::map when you need ordered elements or when you require range queries, as it maintains sorted order.
