Is it OK to use C-style cast for built-in types?

Question

After reading here a lot of answers about C-style casting in C++ I still have one little question. Can I use C-style casting for built-in types like long x=(long)y;

Answer 1

Why do you need that particular cast? Any numeric type can be converted to a long without a cast (at potential loss of precision), so casting doesn't let the compiler do anything it can't already. By casting, all you do is remove the compiler's ability to warn if there is a potential problem. If you're converting some other basic type (like a pointer), to a long, I'd really like to see a reinterpret_cast<> rather than a C-type cast, so I can find what's going on easily if there turns out to be a problem.

I'm not going to approve of casting without a reason, and I'm certainly not going to approve of C-type casts without a good reason. I don't see a reason to cast between most built-in types, and if there is one I want to be able to find it easily with a text search.
