Thread: dequeue

the character value stores a name of user and the j stores his/her age.
those two things stored in queue.
I need to pop first data in queue and display them to the screen.
but I can not figure out how to return two different types of values. Is there someway I can return Character value and interger?

Code:

char dequeue(struct queue *q)
{
	char name[25];
                int i;
               int j;
	struct customer * tempPtr;
    
	for(i=0; i<25; i++)
	name[i] = q->front->firstname[i];
                 j = q->front->num;
	tempPtr = q->front;

	q->front = q->front->next;
	if (q->front == NULL)
		q->rear = NULL;
	free (tempPtr);
	return name;
}

you mean return char OR value into a variable? or char AND value into separated variable?

char OR value into a variable
> try declar the variable as character

char AND value into separated variable
> there's no any clue to return 2 value. but by using pointer you may fix this problem. for eg:

Code:

int main (void)
{
..
..
function (&char, &int);
..
..
}

void function (char *a, int *b)
{
..
..
printf ("enter character > ");
scanf ("\n%c", &*a);
..
printf ("enter integer > ");
scanf ("\n%d", &*b);
}

There are a bunch of ways to return more than one value, the best in this situation is to pass the address of the variables to the function and just change them:

char dequeue ( struct queue *q, char *name, int *j );
