Web为什么std::set允许在与set元素不同的类型上使用lower_bound() 因为它很有用，而且可能更有效率。 例如，考虑一组std::string。创建(大型)字符串是很昂贵的。如果有字符串视图，则可以使用std::less<>将视图与集合的字符串进行比较，而不必从该视图构造字符串。 Web1 day ago · This works great, but Static constexpr members must have in-class initializers, so I use have to use a lambda function (C++17) to declare and define the array on the same line. I now also need to include in my header file to use std::array's operator[] overload, even if I do not want std::array included in my application.
