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。
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
so how would you make sure your overloaded functions (where all except one of the overloaded functions act as wrappers to one core function ) work with C?Example:Assume foo(char *) calls foo (int i) .class Object {public: void foo(int i); // primary function void foo(char *); //...

language that supports function overloading (two functions having the same name, with different parameter lists). From the assembly language programmer’s point of view, the problem with name decoration is that the C++ compiler tells the linker to look for the decorated name rather ...
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 ...
