Compile Header Deed 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.

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.

However usually headers are written so that they are not compiled separately, but only when you include them to source (cpp) files. The only exception is when you want to create precompiled header in g++ - then you must ?compile? header, but the outcome is precompiled header file, but not object file.

In its most basic form, when you compile a Scrivener project, you export it in a form so it can be used outside of Scrivener, but compiling is much more than exporting. (And in Scrivener, export has a different meaning: you export a file or files from the Binder, or you export comments and annotations, etc.)

In C++ programming, it's common practice to separate class interface information into header files. These header files can later be included in programs that use the class. By precompiling these headers, you can reduce the time a program takes to compile.

Only those changed files need to be recompiled. Header files are not compiled directly, Instead, header files are included into other source files via #include .

Yes it is possible to write a simple program without header files, but why would you do that ? Header files are useful to share definitions, constants, functions prototypes, etc between multiple files or modules.

A header file looks like a normal C file, except it ends with . h instead of . c , and instead of the implementations of your functions and the other parts of a program, it holds the declarations.

The header file contains only declarations, and is included by the . c file for the module. Put only structure type declarations, function prototypes, and global variable extern declarations, in the . h file; put the function definitions and global variable definitions and initializations in the .
