real:0 imagenary:12 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...
1)For operator overloading to work, at least one of the operandsmust be a user defined class object. 2)Assignment Operator:Compiler automatically creates a default assignment operator with every class. The default assignment operator does assign all members of right side to the left side and wo...

三者都是计算机的编程语言 C语言是基础语言 C#和C++是高级编程语言，C语言是面向过程的，主函数和函数的调用，但是C#和C++是面向对象的，可以通过类创建对象来实现相关功能，他们具有抽象性、封装性、 继承性 、多态性， 比起C语言来说跟复杂些。C语言是面向过程的。C++是C语言的升级版，C是C++的子集...

The upcoming 0.7.x releases will focus on expanding the standard library, fixing bugs and improving compile time analysis. Follow...
虚函数(virtual function)、运算符重载(operator overloading)、多重继承(multiple inheritance)、模板(template)、异常(exception)、RTTI、名字空间(name space)逐渐被加入标准。1998年国际标准组织(ISO)颁布了C++程序设计语言的国际标准ISO/IEC 14882-1998。遗憾的是,由于C++语言过于复杂,以及他经历了长年的演变,直到...

The C++ compiler in Visual Studio 2012 detects that A isn't implicitly convertible to C, and removes the pair conversion from overload resolution. This change is a positive for many scenarios. For example, overloading func(const pair<int, int>&) and func(const pair<string, string>&), ...
For example, overloading func(const pair<int, int>&) and func(const pair<string, string>&), and calling func() with pair<const char *, const char *> will compile with this change. However, this change breaks code that relied on aggressive pair conversions. Such code can typically be ...
