Thread: 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.

Code:

int setCardinality(int a[]){
	
	int i;
	int numberElements=1;

	for(i=1;a[i]!=-1;i++){
		numberElements++;
		
	}
	return (numberElements);

}

void printSet(int a[]){

	int setCardinality(int a[]);
	
	int j;

	for(j=0;j<setCardinality(/*here*/);j++){
		printf("%d,", a[j]);
	}
	printf("}\n");
}

I may be misunderstanding you here, but is this what you are looking for?

Code:

for(j=0;j<setCardinality(a);j++)

Code:

for(i=1;a[i]!=-1;i++)

Is this intentional? Array indexes start at 0, not 1.

Code:

int setCardinality(int a[]);

There's no point for this prototype to exist in the middle of a function block.
