1. How to avoid precompiled headers

You can always disable the use of pre-compiled headers in the project settings.

Instructions for VS 2010 (should be similar for other versions of VS):
1. Select your project, use the "Project -> Properties" menu
2. go to the "Configuration Properties -> C/C++ -> Precompiled Headers" section,
3. then change the "Precompiled Header" setting to "Not Using Precompiled Headers" option.
2. Visual Studio: Disable Precompiled Headers
1. Open your project, then select “Project” > “appname Properties…“.
2. Expand “Configuration Properties” > “C/C++” > “Precompiled Headers“.
3. Set “Precompiled Header” to “Not Using Precompiled Headers“.

3. What are these .pch and .ncb files in visual studio?

PCH is the precompiled headers file. It's a temporary that you can safely delete. You can disable its creation through Project Settings > C++ > Precompiled Headers > Don't use precompiled headers and removing the stdafx.cpp file from your project.

NCB is the database used by IntelliSense to allow you to browse the symbols defined in your project, including the inline hints and auto completion as you type. You can safely delete it. There is an option to disable IntelliSense too.

However, both features may be useful; therefore you may not want to disable them. If you worry about the size of the backups or sending the projects to some other programmer, then you can just clean the project by removing said files.
