    Calling functions within functions

    I have two functions. I have 2 arrays in int main. Now I need to pass both arrays individually to these two functions. Everything is fine with the first function. On the second function, I am calling the first function within this function. My question is, what do I put in the spot, marked "/*here*/"? The matrices are a and b. I need to let it use whatever array was passed to the function, so I dont know what to put there, or what else can I do?

    I probably didnt explain it well, so let me know if I need to do more explaining. Thanks for help.

    int setCardinality(int a[]){
    	int i;
    	int numberElements=1;
    	return (numberElements);
    void printSet(int a[]){
    	int setCardinality(int a[]);
    	int j;
    		printf("%d,", a[j]);

    I may be misunderstanding you here, but is this what you are looking for?
    Is this intentional? Array indexes start at 0, not 1.

    int setCardinality(int a[]);
    There's no point for this prototype to exist in the middle of a function block.
