C + WINAPI: How To handle Files?

OK, I have read about CreateFile, R开发者_JAVA百科eadFile and WriteFile and I know how to use these. But I could not find any tutorial or guide with an example to use them properly. How do I handle files? I want to learn about:

1. Read strings from file.
2. Write strings to file.

How does one do that?
