When the function returns, it contains pointers to twoCAnimationVariableobjects representing the X and Y coordinates. CAnimationPoint::GetDefaultValue Returns the default values for X and Y coordinates. C++ CPointGetDefaultValue(); Return Value ...
Thereinterpret_castoperator should not be used to convert between pointers to different classes that are in the same class hierarchy; use a static or dynamic cast for that purpose. (reinterpret_castdoes not perform the adjustments that might be needed.) This is illustrated in the following exampl...

Function pointers and Argument Deduction通过函数指针赋值，可以直接实例化一个模板函数，如下template <typename T> int compare(const T&, const T&);int (*pf1)(const int&, const int&) = compare上面会直接实例化参数 T 为 int 的 compare 函数Template Argument Deduction and References分函数参数为左值和...
