C/C++中的函数重载(overloading) 几年前,我已经介绍过如何使用const和volatile限定词声明数据。使用这些限定词来声明数据,产生的影响会波及到函数的声明。在C和C++中,影响是不一样的,很大程度上是因为C++中的函数声明比C有更多的功能。为了更清楚描述清楚影响的不同,我们先来看看C和C++中函数最主要的差异是什么。

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...

When this new behavior causes overload resolution to consider an additional candidate that's equally as good as the historic candidate, the call becomes ambiguous and the compiler issues compiler error C2668 as a result. Output Copy error C2668: 'function' : ambiguous call to overloaded functio...
For C++,dbxhandles the implicitthispointer, default arguments, and function overloading. The C++ overloaded functions are resolved automatically if possible. If any ambiguity remains (for example, functions not compiled with-g),dbxdisplays a list of the overloaded names. ...
了解隐式接口和编译期多态(class 和 templates 都支持接口(interfaces)和多态(polymorphism);class 的接口是以签名为中心的显式的(explicit),多态则是通过 virtual 函数发生于运行期;template 的接口是奠基于有效表达式的隐式的(implicit),多态则是通过 template 具现化和函数重载解析(function overloading resolution)发...
