In member function of class, if type of parameter is the same class or base class, parameter’s private or protected data member can be visited directly in member function, else it is not allowed. Void Dragon::
we have created a class template Number with the code;template <class T> class Number { private: T num; public: Number(T n) : num(n) {} T getNum() { return num; } };Notice that the variable num, the constructor argument n, and the function getNum() are of type T, or have...
It is a “do nothing” function. It only provides the template in the base class, and its implementation is provided in the derived class. A pure virtual function cannot be global or static. It helps us achieve polymorphism in our programs, and this concept comes under run-time polymorphism...
// The code in the generic f will fail // with C2248: 'Array<T>::size' : // cannot access private member declared in class 'Array<T>'. //friend void f<int>(Array<int>& a); friend void f<>(Array<T>& a); }; // f function template, friend of Array<T> template <class ...

c++ 模板<template class T> 在c++中有如下语句 int a; char b; long c; float d; 像上面的 int, char, long, float 被称为“类型”。 有时需要将“类型”也做为参数来处理,比如,要写一个比较大小的函数 comp(x,y) 如果是两个int型比较就返回一个int类型的值,如果是两个float型比较就返加一个...
class factories are specialized using theCFactoryTemplateclass, also called thefactory template. Each class factory holds a pointer to a factory template. The factory template contains information about a COM object, including the object's class identifier (CLSID) and a pointer to a function that ...
