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 ...

方法重载(overloading)必须满足()A.在不同class中定义的方法B.在同一类型中定义的方法C.方法名必须相同D.返回类型必须相同E.参数一定不同F.参数可以
Now the C++ overloads have been removed from <math.h> and are only found in <cmath>. To resolve errors, include <cmath> to get the declarations of the functions that were removed from <math.h>. These functions were moved: double abs(double) and float abs(float) double pow(double,...
