All Right.

After below modify, notepad++ will highlight c files as c++. But I think it doesn't matter for me read a c file by c++ format.

Well the solution is to edit your langs.xml file in the notepad++.exe directory
<Language name="cpp" ext="h hpp hxx cpp cxx cc" commentLine="//" commentStart="/*" commentEnd="*/">
edit to
<Language name="cpp" ext="h hpp hxx c cpp cxx cc" commentLine="//" commentStart="/*" commentEnd="*/">
The problem is that c extension is associated with c files and you will probably need to remove it from there. After that i think notepad++ will highlight c files as c++.
