Is this a valid C++ code?

I have some errors in the code and am needing some help fixing them. If you have any suggestions please post them. Thanks for any help. Here is the code:

What sort of errors are you getting and what sort of app is this for?
That looks like a mix of Java and C++/Cx (mostly Java). I wouldn't expect this to work.

I'm new to programming and when I downloaded the template it was supposed to be in c++. I just checked it and finally realised it was in java. I've always wanted to make games and I thought it would be a good I idea for my first app that I start with a template and add my information in it. Is there any chance that you could help me develope my first game? (I'm gonna get rid of this...) Thanks for reviewing my question...:)Monday, August 5, 2013 2:53 PM

Start with the Developing games documentation. Post new threads as you come up with more specific questions.
