How do C++ collections compare in terms of performance?

How do C++ collections compare in terms of performance?

C++ offers several collection types like vectors, lists, and sets. Vectors are great for random access, while lists excel in insertions and deletions. Sets provide unique elements with fast lookups. What specific operations are you interested in comparing?

I'm particularly interested in insertion and deletion times.

For insertion and deletion, lists are the fastest since they allow constant time operations at both ends. Vectors, however, can be slower due to potential reallocations. Sets have logarithmic time complexity for insertions and deletions due to their underlying tree structure.

What about memory usage?

Vectors generally use less memory than lists because they store elements contiguously. Lists require extra memory for pointers, while sets can use more memory due to their tree structure. It really depends on your use case!

Thanks! This helps a lot.
