using namespace std bug (.cpp accessing .h files)

Kourosh23 (178)
My .cpp file shows me a bug, and it says a nested namespace should be used, but I don't understand why and how.

Here is the error message and the code:

The error is a "A.h". Probably missing }; at the end of the class.

No, I checked A.h, and I have my }; at the end of the class.

The error is in A.h, show A.h


Also, the line numbers in the error message do not correspond with the code you've posted.

I solved the problem, I needed to include an extra namespace for all my .h files, and then include that namespace in my .cpp file like this:

using namespace test;
