1.string类的初始化操作 首先,在cpp中使用string类 一定需要导入其官方提供的头文件:#include <string> 其次,需要我们注意的两个概念:变量的初始化与赋值是两个不同的操作! 初始化:是在实例化对象时,应该按照初始化的内容来构造;而非先单独构造(此时对象所存储内容没有意义,属于脏数据),有了对象后,进行赋值。 如下,我们直接给

C++/WinRT does have a custom string type called winrt::hstring (defined in the C++/WinRT base library, which is %WindowsSdkDir%Include\<WindowsTargetPlatformVersion>\cppwinrt\winrt\base.h). And that's the string type that Windows Runtime constructors, functions, and properties actually ...
