2.11 — Header files – Learn C++

Writing a header file is surprisingly easy, as header files only consist of two parts: A header guard, which we’ll discuss in more detail in the next lesson (2.12 -- Header guards). The actual content of the header file, which should be the forward declarations for all of the identifiers we want other files to be able to see.

15.2 — Classes and header files – Learn C++

Most often, classes are defined in header files of the same name as the class, and any member functions defined outside of the class are put in a .cpp file of the same name as the class. Here’s our Date class again, broken into a .cpp and .h file: Date.h: Date.cpp:

C++ Header File Guidelines - University of Michigan

Each source (.cpp) file has a header file (a “.h” file) associat-ed with it that provides the declarations needed by other modules to make use of this module. The idea is that other modules can ac-cess the functionality in module X simply by #including the “X.h” header file, and the linker will do the rest.
