    header files

    I have a trivial question.

    I have 10 modules using a .h file.
    if I change a value in the .h file that these modules are using, and then compile one of the 10 modules, then only that module will pick up the new value in the .h file. Am I right?

    so, for the new change to reflect everywhere, do I have to compile all the 10 modules?

    Yes you have to.
    But usually this problem is solved by the dependencies in your build-system.

    If you use an IDE it calls some buildsystem ( like make ) to build your project. If you add the header to the dependancies (spelling ?? ) of each of your source files then all files will be compiled automatically if you build your project and the header has changed.
