Console.WriteLine("This computer is called "& Environment.MachineName) 如果您已經從類別建立物件,也可以透過物件的變數存取Shared成員。 類別和模組之間的差異 類別和模組的主要差異是,類別可以具現化為物件,而標準模組不行。 因為只有一個標準模組資料的複本,所以,當您程式的某一部分變更了標準模組中的公用變數時...
The default allocators supplied with container classes are sufficient for most programming needs. Writing and using your own allocator class is an advanced C++ feature. Example C++ Copy // basic_string_get_allocator.cpp // compile with: /EHsc #include <string> #include <iostream> int main( ...
