#define statements within a namespace

Question

If I have a #define statement within a namespace as such:

namespace MyNamespace
{
  #define SOME_VALUE 0xDEADBABE
}

Am I correct in saying that

Answer 1

Yes. In general, using const values instead of #define'd values has many advantages. Restricting the scope of the variable is one of the advantages. The scope can be restricted to a namespace, or to any another valid scope this way (including at the class level, function level, etc).
