Huge array on C++ -



Huge array on C++ -

i solve problem using c++. have huge array of double-s. used during process of solution, programme adresses different parts both reading them , changing ones.

what type of container proper situation? must access elemetns quilckly , store info properly.

is thought utilize std::vector<double>?

it depends on , how perform operation on container. like:-

associative container std::set efficient in case implemented in terms of balanced binary tree.

but sorted vector outperforms associative container in situations on basis of locality of reference.

if operation on info construction categorized below sub-operations utilize sorted vector:-

1) there insert/delete set info structure.

2) after info construction setup operations predominant.

note: should initialize vector big plenty avoid re-allocations in between.
