Friend class

Hello people,

I am trying to work with a friend class but for some reason when I want to cout my variable of interest it returns a memory space (I think so)
Can anybody help me?

PopulationFrequency::arraysize is an int, it won't write a space. You need to double check your output.

Also, don't use friends. It's almost always used inappropriately.
