What you get when you use C or C++ is a defined interface that will make available to you a function printf that will behave in a well-defined manner. Whether the actual source of printf is written in C or assembly or Pascal or whatever is not supposed to matter.

One place you can start with is at the following address:
http://www.koders.com/c/fid4E0FA789459803C1E4369279B96E5C9B257941C8.aspx?s=printf#L7
That one is the GNU C's implementation. I think you probably find your way from there on to scanf. And doing a google on the file name gives more results I bet.

Why not run your code via the debugger and when you get to the printf function step into the function. If on your machine your compiler has the full source code for the libraries (i.e. Win SDK), then you should find the code.
Maybe.

I can easily see this thread being kept alive for four more years with "me too!" posts, so I'm closing it.
