1. 32-Bit or 64-bit OS ?? Updated: 13 Oct 2010 In .NET 4.0, you can also use the new System.Environment.Is64BitOperatingSystem and System.Environment.Is64BitProcess C++, C#, .NET	Reinhard Ostermeier
2. 32-Bit or 64-bit OS ?? Updated: 19 Sep 2010 In C++ you can use the size of a pointer to work out what sort of process you're running in:bool is_64_bit(){ return sizeof(void *) == 8;}This has got the advantage of being portable and you don't have to call any OS functions.You can do something similar in C - just return...
