True. &nbsp;I'm not denying that, I'm just point out that that information is not of much importance to a program runing in windows. &nbsp;So if you think your program really needs this information, you are probably wrong. &nbsp;(I also don't know how to get the information, there are not procedures I know of that return it, you can probably find it somewhere in the registry.) &nbsp;

As to know Which size of RAM?

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
