有没有办法访问已隐藏在另一个作用域内的局部变量的值？ [英] Is there a way to access the value of a local variable that has become hidden inside another scope?

问题描述

我知道变量是否为全局变量，您始终可以通过在变量名称前添加 :: 来访问其值...但是有一种方法可以访问

I know if a variable is global, the you can always access its value by preceding the variable name with ::... but is there a way to access the value of a local variable that has become hidden inside another scope?

我在想这样的事情：

void f() {
    int x = 1;
    {
        int x = 2;
        //access the value of the variable x (with the 1 in it) inside here
    }
}

如果该语言不支持此功能，那么我可以使用一些hacky解决方案。

If the language doesn't support this, then I'm perfectly okay with some hacky solution.

推荐答案

我认为C ++不支持此功能。

I think C++ doesn't support this.
