Compile Header Deed For Free

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.

A compiler takes the program code (source code) and converts the source code to a machine language module (called an object file). Another specialized program, called a linker, combines this object file with other previously compiled object files (in particular run-time modules) to create an executable file.

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.

1 Answer Click the "Project" tab, it's in the top right side. Within the "Project" tab click the "Add Files..." option. Highlight your Header file and any other files associated with your header file, like if you put your header files definitions in a . cpp file. Compile and Run.

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.

Header files are nothing more than inserting the contents of them at the place where you use #include . You can write all that on your own if you want to.

Header files should #include the minimum header files necessary, and source files should also, though it's not as important for source files. The source file will have the headers it #include s, and the headers they #include , and so on up to the maximum nesting depth.
