Question

Sorry this is a basic question, but all my research just barely missed answering my question and I just wanted to double check before I write all my code with an assumption.
I’m using C and I have a header file with some variables declared (ints, char arrays, int arrays). If I have a function that makes use of these global variables I am assuming that I can use the variables without passing them?

EXAMPLE
HEADER FILE:

int state;
int lnArray[];

C FILE:

void function(){ 
    int i;
    for(i=0;i<5;i++;){
        if(lnArray[i]<10)    
        state = lnArray[i];
    }
}

Answer 1

That’s correct. It’s why they’re called “global” variables: they’re available in any scope.
