How does C++11 std::vector compare to other 2D data structures in terms of performance?

How does C++11 std::vector compare to other 2D data structures in terms of performance?

C++11's std::vector offers dynamic sizing and good cache performance, but how it compares depends on the use case.

What are the advantages of using std::vector over arrays for 2D data?

std::vector provides automatic memory management, bounds checking, and easier resizing compared to raw arrays.

Are there specific scenarios where std::vector performs poorly?

Yes, in scenarios with frequent insertions and deletions, std::vector may incur performance penalties due to reallocations.

How does std::vector's performance compare to std::array?

std::array has better performance for fixed-size data due to no dynamic allocation, but lacks flexibility.

Can you provide benchmarks comparing std::vector and std::array?

Sure! Benchmarks typically show std::array outperforming std::vector in fixed-size scenarios, especially in tight loops.
