How can I return two elements using function?

Question

https://code.sololearn.com/cNeY9b8M2s1M/?ref=app
Here in this code, I'm returning an array. But I also want to return n, which is the number of elements in the array.
How can I return these two elements?

Answer 1

Martin Taylor what do you mean by passing the size variable as pointer in arguments?
Do you mean by creating a new function by passing the arguments as the size and returning the size value again?

Answer 2

You can use struct or union to do that

Answer 3

「ＨＡＰＰＹ ＴＯ ＨＥＬＰ」 can you please explain how can I implement it in my code, how can I pass in a variable by reference and overwrite it.
Can you explain it more elaborately.

Answer 4

Martin Taylor Why did you call the argument with an address?
array=getarr(&arraysize);

And why are we declaring it as a pointer? int* getarr(int *sz);

I think you are returning the value as you used the pointer again, *sz=50;

But why aren't we just using int without pointers and address?

Could you please explain this flow of code again and correct me if I'm wrong too.

Answer 5

Martin Taylor Thanks it works perfectly now. I got a bit confused as you passed *sz=50; as i originally asked to pass the value of n, which is the number of elements in the array :)
