How to know the type of variable at run time??

[ashishbhatt12]

Hi All,

I am using VC++ MFC Application.

I want to know the typeof my variable at run time, how can I do that? I hope it is possible with the typeof operator, but it gives me error like this identifier not found.So, is it possible with VC++ to use something like typeof operator??

Thanks in Advance.

How did you get in this pickle? Usually in C++ if you need to know the type of the object your design is faulty.

Besides, the typeid operator only works if your class has virtual methods. The reason is that the derived object may be known only by a base class pointer.

If your class does ot have virtual methods, then you already know the type.

use dynamic_cast...

if (dynamic_cast<type>(var))
{
  // 'var' is an instance of 'type'
}
