Depth about it can be explained with an example.
Lets we define a Class A in file a.h and its function definition lies in a.cpp
Then when you compile and create the library the definition of function lies in the .h files and the implementation lies in the lib files.
Like say iostream.h files hold the function signatures of the function and the corresponding lib files has the actual implementation of the function.
