How does C++11's std::vector perform with 2D data?

What are the performance benefits of using std::vector for 2D arrays in C++11?

Using std::vector in C++11 for 2D arrays provides dynamic sizing, better memory management, and improved cache performance.

How does std::vector compare to traditional arrays in terms of speed?

While traditional arrays can be faster for fixed sizes, std::vector offers flexibility and can be optimized for speed with proper usage.

Are there any downsides to using std::vector for 2D data?

One downside is the overhead of dynamic memory allocation, which can impact performance if not managed properly.

What are some best practices for using std::vector with 2D data?

Best practices include reserving space, using emplace_back for insertion, and avoiding unnecessary copies.
