I'm studying c++ at the moment. What are you learning?
C++ is a great choice. It can be applied to anything and everything. I enjoy JavaScript. 
Oh when did you learn Java?
I just started. I should look into c++. How long have you been learning it? 
I been learning for 2 months or so. I'm not that great yet.
Variables and datatypes can be confusing but arrays are fun to learn. 
Yeah, I've been learning about them. Arrays are confusing for me too. 
Sometime it is better to think of it as just an ordered list. Just make sure it always includes the same type. 
What about datatypes? I find those ones confusing to learn too. Do you have any advice?
Making sure to fully understand the two data types. Both primary and derived data types. They seem similar but are actually quite different. 
Ahh okay. I'll keep that in mind when studying. Do you have any books you'd recommend for learning about Java?
"Effective JavaScript" by David Herman is a great one. Easy to understand. 
Do you know where I can buy used copies of it?
I would check out Amazon! 
Do they carry a lot of books about computer science there?
They really do. They also have a great recommendation function to find similar books. 
That's great. I see a book on there called Computer Science Distilled. Do you think that would be a good for overall learning about computer science?
