Can anyone tell me some advantages and disadvantages of those two programming brands?

Java is slow and bad at numbers; C++ is fast and exellent at it. C++ is generally hard to port from system to system (if you use certain subsets of it, it's not too bad); Java is easy to run most anywhere. C++ is hard to write if you manage your own memory; Java does this for you. Bad: Java is programming with kid gloves on. C++ is oldfashioned. Good: Java is interoperable and C++ is blazing fast. Between the two, I prefer C++.

How do I install C++ into my computer, so I can use it?

Wait, microsoft actually has a free program?! Quick, call Bill Gates' doctor! I think Mr. Gates is ill!

A professor recently told me that java benchmarks are actually getting very close to C... Have any idea where I might confirm or deny that?

My C++ programs go 1.5 to 2 times faster than my C# programs, which are maybe 20% faster than my Java programs.

Considering that Java runs on top of other things, this would make the most sense.
