ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

I am using semaphore.h
I declared a variable of type sem_t.
I am able to use the variable without even calling sem_init or sem_open, and it is working properly.
Can somebody explain to me if the variable is automatically assigned some value?
Also would I run into any trouble doing so?
It is assigned the value there was in the memory previously. So, normally you can't predict it. Sometimes that may work, but at some point you'll very likely start getting errors/strange behaviour.
