A void function passes three parameters in this order: A vector of integers, an empty array of integers, and an int that stores the number of elements of the array.

The function copies all the elements stored in the vector into the array.

Example:

Vector contains => 7 5 2 9 6 Array is empty. Function runs... Vector contains => 7 5 2 9 6 Array contains => 7 5 2 9 6

Which is the best way to pass vector?

Which is the best way to pass array?

Which is the best way to pass the integer storing the number of elements?

If kindly explain much appreciate.
