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。
Overloaded functions and operators are described in Overloading functions (C++ only) and Overloading operators (C++ only), respectively. An overloaded declaration is a declaration that had been declared with the same name as a previously declared declaration in the same scope, except that both ...
答:构造器Constructor不能被继承,因此不能重写Overriding,但可以被重载Overloading 21、是否可以继承String类 答:String类是final类故不可以继承 22、try {}里有一个return语句,那么紧跟在这个try后的finally {}里的code会不会被执行,什么时候被执行,在return前还是后 答:会执行,在return前执行 23、用最有效率的...

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...
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>&), ...
