Compile Header Statement Of Work For Free

You don't need to compile header files. It doesn't actually do anything, so there's no point in trying to run it. However, it is a great way to check for typos and mistakes and bugs, so it'll be easier later.

Header files aren't compiled unless pulled into a translation unit via #include preprocessing. Since your only . cpp file has no such inclusion, it is not compiled, and therefore nothing within is available to that (and apparently your only) translation unit.

H. DON'T include any executable lines of code in a header file, including variable declarations. But note it is necessary to make an exception for the bodies of some inline functions, about which more below.

Only source files are passed to the compiler (to preprocess and compile it). Header files aren't passed to the compiler. Instead, they are included from source files.

Headers include: Title of Document. Sub-Title or Chapter or Section....Footers include: Name of Author (very important) Date of Publication. File Name (optional) Version Number (optional) Page Number.

Since a typical header file usually contains only declarations that can be safely repeated in each translation unit, it is perfectly expected that "compiling" a header file will have no harmful consequences. But at the same time it will not achieve anything useful. Basically, compiling hello.
