static_cast vs. dynamic_cast and reinterpret_cast

[Gorgor]

Let's suppose I have an array of a base class, but it's filled with derived classes. I'll use only one derived class, but suppose there are several types.

Edit: wrong! CBase myArray[MY_ARRAYSIZE];

What I meant:  CBase *myArray[MY_ARRAYSIZE];

...

reinterpret_cast<CDerived *>(myArray[i])->derivedFunction();

According to the descriptions of the various castings, this is the wrong thing to do since it doesn't "climb the trees" to return the correct pointer (where a pointer to the derived might actually != pointer to the same object's base!)

So I'd want to use dynamic_cast or static_cast instead (static_cast would be good enough for this particular application.)


More importantly, reinterpret_cast is wrong to use in this situation always?
