WebThis code is not very readable, take a look on this which is C++ and it is written to be more readable. Basically algorithm is same, but information is not stored in bits (there is no point in case constexpr). Change std::array to std:vector and you have version, where flags are stored in single bits. – Marek R May 21, 2024 at 9:35 1 WebJul 28, 2024 · This article will explain how to implement the sieve of eratosthenes algorithm in C++.
