What factors affect the performance of C++ std::vector?
The performance of C++ std::vector can be influenced by factors like memory allocation, resizing, and element access patterns.
How does resizing impact performance?
Resizing a std::vector can be costly because it may require allocating new memory and copying existing elements to the new location.
Are there ways to optimize std::vector usage?
Yes, you can optimize std::vector by reserving space in advance, minimizing resizing, and using emplace_back instead of push_back.
What about the performance of std::vector compared to other containers?
std::vector generally offers better performance for random access and cache locality compared to other containers like std::list.
