namespace

[sw21]

Hey
I was wondering why this is possible :

class A{
public:
	int iAddition2(int arg1, int arg2) {
		return iAddition(arg1, arg2);
	}
	int iAddition(int arg1, int arg2) {
		return arg1 + arg2;
	}
};

and not this:

namespace myNS {
	int iAddition2(int arg1, int arg2) {
		return iAddition(arg1, arg2);
	}
	int iAddition(int arg1, int arg2) {
		return arg1 + arg2;
	}
}
