DSA in CPP

So i started dsa in cpp but now as i was learning the language I came across std::array and c style arrays. Vector obviously are the best but for constexpr , std::arrays are good. WHAT is then need of c style arrays here, should i learn it or just skim it. Yeah ik std::arrays are structs who are just T arr[N] but how will this help me in dsa,etc. My plan is to skip cstyle arrays. Just guide me . submitted by <a href="https://
