What is an alternative to containers from the stl library?

Question

C++ / C#

I need to implement some task with the condition of not using stl library containers. What library is better to use as an alternative to stl ?

Answer 1

Tasks that stipulate a ban on the STL involve checking whether the examinee is familiar with the STL only from the side of use or understands how it works from the inside.
And not a check to see if the cunning person has the audacity to replace the STL with a "different library".

Answer 2

Boost, Qt, Facebook Folly, Eigen - a huge number of libraries provide containers of varying degrees of crappiness. But judging by the wording of the task, you will be expected to write new[] (citizens who write malloc in C ++ expect a fun UB when they mix it up and call delete instead of free ) and roll the container with your own hands.
