signatures of the declaring and implementing partial constructors must match according to the rules ofpartial members. The defining declaration of the partial constructor can't use the: base()or: this()constructor initializer. You add any constructor initializer must be added on the implementing ...
when there is just one expression in the initializer list, remove the braces from it. f(3); } 这一新行为会导致重载解决方法要考虑比以往候选更适合的其他候选时,调用将明确地解析为新候选,导致程序行为的更改可能与程序员的需要有所不同。 示例2:重载解决方法的更改(之前) C++ 复制 // In ...
There also may be runtime differences, because use of {} to initialize may call a constructor that takes a std::initializer_list, instead of the default constructor. The conforming behavior is enabled under /permissive-.Here's an example of the changed behavior:...
