template< class T = void > struct plus; (C++14 起) 进行加法的函数对象。相当于在两个 T 类型的实例上调用 operator+。 特化标准库在不指定 T 时提供 std::plus 的特化,这令形参类型和返回类型留待推导。 plus<void> (C++14) 实现x + y 的函数对象,推导形参类型和返回类型 (类模板特化) (C+...

刚刚在看《C++语言导学》看到了complex库,还以为是什么新特性去向室友宣传,之后才知道是我学艺不精了。所以特意去看了cppreference和microsoft文档去学习了一下。以下简单记录一下个人想法 先贴一下gcc中的部分源码 template<typename_Tp>structcomplex{/// Value typedef.typedef_Tp value_type;/// Default constructo...
