Performance Comparison of C++ Containers

What are the performance differences between std::vector and std::list in C++?

std::vector is generally faster for random access and iteration, while std::list excels in insertions and deletions.

How does std::deque compare to std::vector?

std::deque allows fast insertions and deletions at both ends, but std::vector is more efficient for contiguous memory access.

What about std::set and std::unordered_set?

std::set is ordered and uses a tree structure, making lookups O(log n), while std::unordered_set is faster with average O(1) lookups.

Which container should I use for a large dataset?

For large datasets, consider std::vector for performance unless you need frequent insertions/deletions, then std::list or std::deque might be better.
