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。
Range-Based for loop : 基于范围的for循环 structured programming:结构化编程 building block:构建单元 Call-by-value:传值调用 Pass-by-value:传值 Pass-by-Reference:引用传递 move semantic:移动语义 expression template:表达式模板 function overloading:函数重载 overload resolution:重载解析/重载决议 Implicit C...
Default parameter values are also penalty-free. The compiler simply inserts code to pass the default value whenever the function is called without an argument in that position. Similarly, function name overloading is a compile-time modification. Functions with the same names but different parameters...
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 ...
