访问实例化它的类中的变量 [英] access variables in class that instantiates it

问题描述

class B;

class A 
{
	public:
	int x, y;
	B b;
}

class B 
{
	func func1();
}

在func1中，如何访问在类A中定义的变量x或y?

/EDIT M-看起来像重新发布 [

In func1, how to access variables x or y defined in class A?

/EDIT M - Looks like a repost[^]

推荐答案

创建实例类A并对其进行访问.我的C ++可能有点生锈，但这就是它的精髓.

A a = new A();
a.x = ...
a.y = ...

仅仅因为您在A中有一个B实例并不意味着您可以从B中自动访问A中的任何内容.就我个人而言，我很可能将值传递给func1

func1(int x，int y)

Create an instance class A and access them. My C++ may be a little rusty, but that''s the jist of it.

A a = new A();
a.x = ...
a.y = ...

Just because you have an instance of B in A doesn''t mean you can automatically access anything in A from B. Personally I would probabably pass the values to func1

func1(int x, int y)
