operating system

Question

hi ,

can u tell me in which language Operating System is developed ?

Windows Xp and Windows 7

Answer 1

Most of the code in the Windows kernel is C, there is some C++ and some assembler.   In user space I beleive it is similar, but there may be other languages involved.

Answer 2

As Don states, in the kernel you use C, C++ is discouraged, though that may change in Win 8, and while assembly is possible it's more of an exercise in futility. As to applications, MFC is available, but more emphasis is placed on managed code using either C++ or the preferred C#.

I'm not sure that's really the right word.  The KS audio, AVStream and BDA

samples in the WDK have always been in C++.

 

We need to work "lukewarm", "ambivalent", or "conflicted" in there somehow.

Answer 4

if some part of OS is developed using c#, if it is managed code then Framework need to be install to run the program right?(whether bydefault while installing OS it will install the framework?)

any feature of WPF added in Windows 7 because look and feel of OS is totally different from XP ..?

Answer 5

there are very few parts of the OS that are in C#, primarily media center is one of the only C# applications in the OS. the changing of the UI/look and feel is done in C with theming support that is private to the OS, nothing like WPF

The desktop is now drawn by a Direct3D application, and application windows

are stored in textures.  That's where the transparency comes from.
