    Do cpp Files get Included Automatically in VS?

    Hi,

    I've copied this example program out of a book, and it's made up of 3 files:

    Fract.h, FloatFract1.cpp, and Fract.cpp

    I've been using VS Express to put it all together into a project. This may be a stupid question, but when you build your solution, do all the cpp files get put together automatically?

    I understand that you have to put #include "Fract.h" or the same for your other header files. But I've noticed that there's nothing like: #include "FloatFract1.cpp" or #include "Fract.cpp" in the files. So do .cpp files just get included together automatically?

    Thanks.

    Compilation is a two step process. In step #1, individual cpp files are compiled to produce obj (object) files. In step #2, the linker combines these obj files together to produce an executable.

    It's step #2 where the cpp files get "put together automatically." And yes, if the relevant cpp files are included in the project, they will be used to produce the final program.
    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}
