The.h files are used to expose the api of a program to either other part of that program or other program is you are creating a library For example, the program pizzadelivery could have 1.c file with the main program, and 1.c file with utility functions. Typically, a.h.in file is a header template that is filled in to become the actual header by a configure script based on the outcome of several tests for features present on the target platform. I've always used a *.h file for my class definitions, but after reading some boost library code, i realised they all use *.hpp I've always had an aversion to that file extension, i think mainly be. When dividing your code up into multiple files, what exactly should go into an.h file and what should go into a.cpp file?
