the default new operator is not quite fit for the project / program, because allocating memory will cause the platform implementation searching for free memory bulks, merging fragments. These may be time consuming. To get good performance and control, people may need customize the new...
第17行使用member function的方式overload + operator,18行使用global function的方式overload * operator,這兩種寫法都可以,惟若使用global function,由於要存取data menber,所以要宣告該function為friend,這樣才能存取data member。 19行我們overload了<< operator,由於也是global function,所以也要宣告friend。 最後49行...
为类型转换运算符函数添加explicit修饰符,表明此函数仅支持显式类型转换。通过这种机制可有效地防止误转换。 范例:OperatorTypeConversion04.cpp 说明:此特性要求编译器支持C++0X标准,g++ -std=c++11 OperatorTypeConversion04.cpp。 解引用操作符(*和->)与智能指针 Smartptr.cpp、auto_ptr 函数操作符 Square.cpp ne...
他们都可以看做是ostream对象//友元friend表示这个函数不是类的成员函数,而是一个全局函数,//而且可以访问类的私有成员:不然在函数内访问类的私有成员就只能写stu.get_id() stu.get_name() stu.get_age()这样的代码friendstd::ostream&operator<<

newMatrix[x, y] = mat1[x, y] + mat2[x, y];returnnewMatrix; } The operator isstatic, which is the only way it can and should be declared because an operator belongs to the type and not a particular instance. There are just a few rules you have to follow when implementing operator...
