So casting is a bad idea?
Not at all, but you need to understand what you are doing when you use it. A cast is used to tell the compiler that you want to treat one object type as another, and that you understand the potential side effects.

What exactly is the difference between cast and redefinition?
Not sure I understand what you mean by "redefinition" in this context.

Vaclav_Sal wrote:
I pass a pointer to this int array either by redefining it as double or as a cast.
That does not make sense, you cannot use a cast to pretend that an array of integers is an array of doubles, they are totally different types.
