C++20 std::map::contains
1.
contains() member function of
associative containers, e.g. std::map::contains()
2.
추가한 이유 - 기존
코드가 지저분해서 의도가 불분명함 - QT 의 QSet, QMap 에 이미 contains 함수가 있고 널리 쓰이고 있다
3.
contains() 가 추가된
컨테이너들 std::map std::multimap std::set std::multiset std::unordered_map std::unordered_multimap std::unordered_set std::unordered_multiset
