Hello, this is the question:
when you compile different modules (.obj) and then you link them all to get the executable, how are the globals of each module allocated? Are them global variables or are them static (private) of each module, or anything else?
Thanks a lot for answer.

It depends on how they're declared. Global variables as they're commonly called have static storage duration, but they can have either external or internal linkage depending on whether the declaration is qualified with static or extern or nothing. If a variable has internal linkage, it's only visible within the file in which it was declared. If it has external linkage then it's visible to other files.
