In which language symbian built?

Not really. Visual C++ might have been used to write some of the code on a PC, but most likely CodeWarrior, and then compiled for the phone with GCC (GNU C/C++ Compiler) or RVCT (Real View Compiler Technology from ARM).

In any case, the source code is mostly C++ with some assembly language bits & pieces.

Note that "Visual C++" is a programming tool developed by Microsoft. The programming language is C++ (originally defined by a Dane by the name Bjarne Stroustrup).

Why do you ask?

hi,
Thanks for the reply. I am basically a windows programmer (worked in vc++ now in c#).
I red an interesting book on symbian c++ ( from symbian press itself).
Some base object names used in symbian is same as vc++ and symbian is having exe, dll's etc. So i got this doubt. Moreover i sow nokia's new symbian os mobile ad. that it is having windows media player bulit in. How it is possible? Whether windows mediaplayer is having symbian version also?

Thanks in advance

No Nokia phone will have a Windows Media Player built-in (and there is no Symbian version of it), but the N91 music phone will have a Windows Media Audio codec so that it can play WMA files.
