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。

Name decorationis a standard C++ compiler technique that involves modifying a function name with extra characters that indicate the exact type of each function parameter. It is required in any language that supports function overloading (two functions having the same name, with different parameter li...
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 rest of the overloads were in the <cmath> header. Code that only included <math.h> could have problems with function overload resolution. Now the C++ overloads have been removed from <math.h> and are only found in <cmath>. To resolve errors, include <cmath> to get the ...
That returns a reference to the embedded object (again assuming Data is a nonstatic data member) make the member function nonconst. Same as the previous one, but returns a nonconst reference on an nonconst object Cast constness away with a const_cast<T&>. If you know what you're d...

The notions of program scope and lifetime of variables, together with a discussion of the namespace facility, are the topics of Chapter 8. Chapter 9 extends the discussion of functions introduced in Chapter 7 to introduce function overloading. Function overloading allows multiple function ...
