在C++中制作物体的副本
原标题:Creating a copy of an object in c++

我有一个班子简易通道。 其声明如下:

class SimpleCircle
{
  public:
SimpleCircle();
SimpleCircle(int rad);
SimpleCircle(const SimpleCircle&);
~SimpleCircle();

   SimpleCircle operator++(int);
}

关于定义一的使用:

SimpleCircle SimpleCircle::operator++(int)
{
    简单循环节奏;
    ++itsRadius;
    return temp;
}

当我使用时

简单循环节奏

复印件是否被称作或什么? 在那里发生了什么? 我没有这样的建筑。

简易通道(SimpleCircle)

或(影印厂除外)

最佳回答

这确实称作影印机。 虽然您没有<代码>SimpleCircle(SimpleCircle other),但建筑商界定了你有。 简单通道(简便环形和样);的定义。 The expression *this 能够轻而易举地向该建筑商绘制地图,从而评估在这里所执行的内容。

问题回答

您有一份影印件:<代码> 简便环形(简便环斑);

它可能不以<代码>SimpleCircle为理由,但它经常提及,这是所有影印人的需要。 http://www.un.org/Depts/dpa/index.html。
