这里有6种: | 成员函数 | classC的典型形式 | | ------------------- | ----------------------- | | Default constructor | C::C(); | | Destructor | C::~C(); | | Copy constructor | C::C (const C&); | | Copy assignment | C& oper
Q:What are all the implicit member functions of the class? Or what are all the functions which compiler implements for us if we don't define one? A: (a) default ctor (b) copy ctor (c) assignment operator (d) default destructor (e) address operator Q:What is a container class? What...

CHandle::operator =The assignment operator.Copy CHandle& operator=(CHandle& h) throw(); Parametersh CHandle will take ownership of the handle h.Return ValueReturns a reference to the new CHandle object.RemarksIf the CHandle object currently contains a handle, it will be closed. The C...
CVector (int, int) : x(a), y(b) {} // function name CVector (constructor) CVector operator+ (const CVector&); // function that returns a CVector 上面两个是完全等价的。 当然,定义一个重载运算符,也可以不是类里面的成员函数,要实现上面例子的效果,也可以用: // non-member operator ov...
& operator=(const CSingleton& o) { } }; main() { // These lines will not compile: CSingleton x = CSingleton::GetInstance(); // error: private // copy ctor! CSingleton y = CSingleton::GetInstance(); // error: private // copy ctor! x = y; // error: private // assignment!

ostream&operator<<(ostream& os,constString&str) { os<<str.get_c_str();returnos; }//使用String s1("Hello"); cout<<s1; output 函数,必须为全域函数,这样才能保证是左边调用“<<” 总结 下面,我们回顾一下String 类的设计,设计一个class,首先,我们考虑class中需要什么样的数据,这里是字符串,我们字...
CComBSTR::operator =Sets the m_str member to a copy of pSrc or to a copy of the BSTR member of src. The move assignment operator moves src without copying it.Copy CComBSTR& operator= (const CComBSTR& src); CComBSTR& operator= (LPCOLESTR pSrc); CComBSTR& operator= (LPCSTR pSrc); ...
