Switching from ubuntu to windows

[sancharsharma]

I have learned C++ in ubuntu, Is the knowledge of understanding linux C++ is enough to do programming in Windows C++?

This depends on whether you want to create console applications, applications that use graphics (like OpenGL and DirectX) or applications that use a GUI or some other API (like Win32). It were just for console applications, the difference is negligible. The rest varies depending on what you want to do (and how).
