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

问题描述

我知道如果一个变量是全局的，你总是可以通过在变量名前面加上 :: 来访问它的值...但是有没有办法访问局部变量的值已经隐藏在另一个范围内?

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
    }
}

如果语言不支持这一点，那么我完全可以接受一些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++ 不支持这个.

I think C++ doesn't support this.
