std::unordered_set满足容器(Container)、具分配器容器(AllocatorAwareContainer)、无序关联容器(UnorderedAssociativeContainer)的要求。 成员类型 成员类型定义 key_typeKey value_typeKey size_type无符号整数类型(通常是std::size_t) difference_type有符号整数类型(通常是std::ptrdiff_t) ...
请改用 <unordered_map> 和<unordered_set>。 比较运算符和 operator() 关联容器( 系列)现在要求其比较运算符具有可调用 const 的函数调用运算符。 现在比较运算符类声明中的以下代码无法进行编译: C++ 复制 bool operator()(const X& a, const X& b) 若要解决此错误,请将函数声明更改为: C++ 复制 ...

The call to g uses an overload set that contains two functions, ::f and N::f. Since N::f is a function template, the compiler should treat the function argument as a non-deduced context. It means that, in this case, the call to g should fail, as the compiler can't deduce a ...
