在 C++ 中存储类型
是否可以将类型名称存储为 C++ 变量?例如，像这样:
Is it possible to store a type name as a C++ variable? For example, like this:
type my_type = int; // or string, or Foo, or any other type
void* data = ...;
my_type* a = (my_type*) data;
我知道在 99.9% 的情况下，有一种更好的方法可以做你想做的事，而不必求助于空指针，但我很好奇 C++ 是否允许这种事情.
I know that 99.9% of the time there's a better way to do what you want without resorting to casting void pointers, but I'm curious if C++ allows this sort of thing.
推荐答案
不，这在 C++ 中是不可能的.
No, this is not possible in C++.
RTTI typeid 运算符允许您在运行时获取有关类型的一些信息:您可以获取类型的名称并检查它是否等于另一个类型，仅此而已.
The RTTI typeid operator allows you to get some information about types at runtime: you can get the type's name and check whether it is equal to another type, but that's about it.
