C ++中的公共变量和私有变量 [英] Public and Private Variables in C++

问题描述

我上课.有一个函数和一个变量.

I have a class. There is a function and a variable.

class myClass
{
private:
   int num;
   int Calc(int x);
};

int myClass::Calc(int x)
{
   int num = 12536; //constant
   return num /*First One (Global)*/ + num /*2nd One (1 inside the function*/ + x;
}

现在，如何在Calc函数中同时使用两个变量(数字)?我认为上述功能不正确.

Now, How Can I use both variables(num''s) inside Calc Function ? I think above function is not corrent.

推荐答案

使用:

this->num

推荐您的班级成员.


[edit]
实际上，最好的解决方案是更改名称，以消除任何歧义.

To referance your class member.


[edit]
Actualy the best solution would be to change the names so as to remove any ambiguity.

this->num

虽然也可以.

Will also work though.
