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.
我认为 C++ 不支持这个.
I think C++ doesn't support this.
