Stack and Multiple Queues Syntax

[NICKD54]

Hey guys, I'm working on a program for my computer science class that is based on stacks and queues. Without going into too much detail of what the program is actually supposed to do (I think I understand the algorithm without issues), I just need some help on syntax for functions involving stacks and queues. The professor strongly suggested an array based stack and linked list based queues.


Basically I need to read data in and enqueue it into the first queue. Then I dequeue from there and enqueue into another queue. Our class basically has the functions posted for us.

int enqueue(struct queue* qPtr, int val);

This is where I'm unsure of how to change it. I think I'm supposed to do something like this when I call the function:

int enqueue(struct queue* qPtr, dequeue(struct queue2* qPtr));

Now, what I would like to know is if this is correct, do I need to call the dequeue function before the enqueue function or is calling the enqueue actually called dequeue as well?

Thanks so much for any help!

Unfortunately, no. Recall the difference between declaring a function and calling it.
