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。

function name overloading is a compile-time modification. Functions with the same names but different parameters are each assigned unique names during the compilation process. The compiler alters the
In previous versions, <math.h> defined some, but not all, of the C++ overloads for the math library functions. 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 ...
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...

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 ...
