看到iterator的*、++、--與->等操作,一定會認為iterator就是個pointer,但我翻遍了C++ Primer 4th,就是沒看到它肯定地說『iterator就是poiner』,或說『iterator不是pointer』,留下一個曖昧的想像空間。若以C語言思考,iterator『應該』是pointer。 2.原來會C#、Java,有OO概念 『Everthing is object』,int是object,...
=操作,比较iterator是否到了结尾。 所以这个实现可以如下: namespace BH{ template<typenameT>class ListIter { public: using value_type = T; using reference = T & ; using const_referenct = const T&; using pointer = T * ; using const_pointor = const T*; using size_type = size_t; using...

And in the <iterator>> header, the checked_iterator class is removed, and the unchecked_array_iterator class has been added. The CComPtr::CComPtr(int) constructor is removed. That constructor allowed a CComPtr object to be constructed from the NULL macro, but was unnecessary and allowed non...
