What are the best STL container choices for C++?
It depends on your use case! For dynamic arrays, use std::vector
. For key-value pairs, std::map
is great.
What about when I need fast access and insertion?
In that case, std::unordered_map
offers average constant time complexity for access and insertion.
Are there any containers for fixed-size arrays?
Yes, std::array
is perfect for fixed-size arrays, providing better performance than std::vector
in that scenario.
What about when I need to maintain order?
If you need to maintain order, std::list
or std::vector
are good choices, depending on whether you need fast insertions or random access.
