Single function, Two test cases required

I am a beginner in programming who has just started his classes.
In one of the assignments, we had to write a function to return the average of 3 intergers. Which is not a problem, except that there are two test cases and both have to be passed at once. (1,2,3 average 2. 10,20,30 average 20). I'm not looking for any direct answer but would like to confirm, one function should be able to return only 1 variable if i'm not mistaken? I have tried submitting two functions returning both variables only to have my second function rejected. Ultimately still unable to pass both test case at once.

So what code do you have?

How does this fail for example.

Code:

---

printf("%d\n",average(1,2,3));
printf("%d\n",average(10,20,30));

---

> one function should be able to return only 1 variable if i'm not mistaken?
Yes, that is the case.
To solve this, you can either
• return a structure
• pass pointers to variables where you want multiple answers stored.
