Given that VS2010 is written using itself (and compiled using VC10 compiler, and the code uses new C++0x features such as lambdas, etc), I can assure you that it's quite ready for C++. If you have problems with "Hello, world" applications, then it sounds like a broken install (which is likely a bug), or some post-install bug.
For more information on declarations in C++, see Declarations and Definitions (C++). Here are some common issues and solutions in greater detail. The identifier is undeclared. If the identifier is a variable or a function name, you must declare it before it can be used.

When looking up why C2065 occurred, on the VS docs, my problem never fit any of the criteria for why the issue would occur. The appropriate header file is #included , the class meets the criteria for being declared and defined, and I don't use a pre-compiled header.
maybe you can show me an example of what your asking so i can respond with exact details. as im not sure what your looking for. there is never a point where i say something like Ball aball = new ball(); the only case when i actually try to create a ball is when im adding it to the vector such as AllBalls.pushback(ball(x,x,x,x));
