typedef std::shared_ptr<FinalLightStatus> FinalLightStatusPtr; 1. 这两个语句分别使用了using和typedef来创建类型别名。 using FinalLightStatusPtr = std::shared_ptr<FinalLightStatus>; 1. 这个语句使用了C++11引入的using关键字来创建类型别名,本质上是为std::shared_ptr<FinalLightStatus>这个类型取了一个...
Something like: classSharedDataClass{public:SharedDataClass(constSharedDataClass& other) { data_ = other.data_; }; SharedDataClass&operator=(constSharedDataClass& other) { data_ = other.data_;return*this; }private: std::shared_ptr<DataType> data_; }; I'd like to ask if anyone has so...

任何情况下都不要using namespace std从理论上来说也是有道理的：因为系统库可能会升级，这样升级编译使...

Use a modern programming style, and include the data types operations of the std namespace. For example, Hilo uses the std::shared_ptr and std::vector types.Only the outermost layer of your app needs to use C++/CX. This layer interacts with XAML across the ABI and perhaps with other ...

幼年期的时候尝试自己写了个vector。之后发现所有的测试样例都过了，再后来发现因为using namespace std，...
// Encapsulate it into a shared ptr in order to be able to copy construct / assign auto task_ptr = std::make_shared<std::packaged_task<decltype(f(args...))()>>(func); The next thing we do is we create a std::packaged_task(t). A packaged_task is a wrapper around a function...
