What happens if header file is included twice?

If a header file happens to be included twice, the compiler will process its contents twice.

Can a file other than a .h file be included with #include?

The preprocessor will include whatever file you specify in your #include statement. ... It is, however, unusual programming practice to put any file that does not have a .h or .hpp extension in an #include s
