    "Running a class" is a concept I don't understand.

    Could you take like at least 1 minute to write a clear question ? 15 seconds is not enough if you want other people to understand what you mean.

    I think you mean you want to call two methods at the same time. This is impossible on single core processors. Your operating system tricks you into thinking that it performs many tasks at once.

    To achieve what you want, however, you should look into threads.

    It would help if you told us what OS you plan to run them on, since threads are OS specific.

    If you're from a Java background, note that in C++, you don't run classes, you run functions.

    Well, I don't totally disagree with what you are saying, but you do can find some portable (well, portability is relative; but more portable than using OS specific function calls) thread libraries (example: Boost thread, OpenMP).

    OpenMP is great because it's simple and it does have some acceptable support (Visual Studio and GCC supports it, plus some other compilers that I don't use).
