Size The size, in bytes, of an object of this type. This API was introduced in Visual Studio 14 Update 2 (DkmApiVersion.VS14Update2). (Inherited from DkmNativeCppType) TagValue DkmNativeCppType is an abstract base class. This enum indicates which derived class t...
template<class T,std::size_t N> struct array; 自C++11开始有的。 简介 std::array是一个封装固定大小数组的容器。 这种容器型别其语义与只含有一笔以T[N]表示之C风格阵列做为它唯一非静态数据成员之struct相同。和C-style 数组不同的地方在于它不会自动衰减至类型T*。作为聚集类别,可以使用最多N个可转...
