在声明数据成员之前，成员函数中数据成员的可访问性 [英] Accessibility of data member in member function before declaration of data member

问题描述

请考虑此代码：

class Test
{
public:

Test() { i = 0;  }

private:

int i;
};

甚至在声明/定义数据成员'i'之前。这应该不是编译错误？ （它编译好了！）

Data member 'i' is used even before it is declared/defined. Should this not be a compilation error ? (It compiled fine!!!)

推荐答案

规则是在类定义中定义的成员函数被编译，在类定义之后立即定义。

The rule is that member functions defined in the class definition are compiled as if they were defined immediately after the class definition.
