dynamic cast

[vsgdp]

Must a class have virtual functions to use dynamic cast?

If so, and I need to still downcast between a small hierarchy in which there
are no methods, I should use static_cast ?

It depends on how you use 'dynamic_cast'. For downcasts and cross-casts
- yes, a class must be polymorphic, i.e. it must contain at least one
virtual function. For upcasts this is not required.

If so, and I need to still downcast between a small hierarchy in which there
are no methods, I should use static_cast ?

You can use 'static_cast' in this case, but you won't get any run-time
checking capabilities of 'dynamic_cast'. Decide whether it is really
important in your case.
