A class with 2 names?

Question

While reading code I came across a class which has 2 identifiers 'naming it': ``` class A_EXP Node { //.. }; ``` I am not able to understand what this means. Could someone help me out?

Accepted Answer

`A_EXP` is probably a macro, possibly expanding to nothing at all. It may also expand to a `__declspec` or similar declaration, which modifies how the compiler will emit the class as object code. A common use of this pattern would be:

```
#define A_EXP __declspec(dllexport)
```
