In this program. we have created a class templateNumberwith the code; template<classT>classNumber{private: T num;public: Number(T n) : num(n) {}TgetNum(){returnnum; } }; Notice that the variablenum, the constructor argumentn, and the functiongetNum()are of typeT, or have a retur...
我们已经安装了MFC的源代码,具体路径为:VS的安装路径\VC\atlmfc\src\mfc,如果你本机把VS安装到D:\Program Files(x86)的话,则MFC源代码路径在:D:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\src\mfc。
template<classQ>staticHRESULTCreateInstance(Q**pp);template<classQ>staticHRESULTCreateInstance(IUnknown*punkOuter,Q**pp); 参数 Q 应该通过 pp返回的 COM 接口。 punkOuter [in] 聚合的外部未知或控制未知。 pp [out] 如果创建成功,则为某个接收请求的接口指针的指针变量的地址。

The error message looks very clear to me. You mention a class template named Car, but you haven't provided template arguments for it. In other words, there is no class named "Car" in your program - there is an infinite number of classes named Car<int>, Car<long>, Car<std::string...
显然你你定义了一个Point模版类但在使用它实例化对象时没有加入模版参数。
下列的模板说明中,正确的是( )。 A.template <T1,T2>B.template <class T1,T2>C.template <class T1,class T2>D.template <typename T1;typename T2> 相关知识点: 试题来源: 解析 A [解析] 模板说明,要求每个参数前都有一个类型参数,多个参数需用逗号隔开。
