Answer 1

Adriano Repetti:
"Even if you may see them somehow as equivalent they're completely different in purpose. Let's first try to define what a cast is:

Casting is the action of changing an entity of one data type into another.

It's a little bit generic and it's somehow equivalent to a conversion because a cast often has the same syntax of a conversion so the question should be when a cast (implicit or explicit) is allowed by the language and when do you have to use a (more) explicit conversion?"
