Compile Header Resolution For Free

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.

A header file is a file with extension .h which contains C function declarations and macro definitions to be shared between several source files. There are two types of header files: the files that the programmer writes and the files that comes with your compiler.

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.

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.

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.

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.
