Did i return this array properly

Question

I have to create an array of random numbers, write a function that takes the array as an argument and return only even numbers, while using the function in the program. I used what I think is the passing array method, but I'm not sure if I've done it as I was instructed. Any advice is greatly appreciated.

#include <iostream>

#include <cstdlib>

#include <ctime>

using namespace std;

void evenOnly (int [], int);

int main()

{

   srand(time(NULL));

   int numbers[5];

   int length = 5;

   evenOnly(numbers, length);

   return 0;

}

//srand(time(NULL));

   void evenOnly(int numbers[], int length) {

       for (int i = 0; i < length; i++) {

           numbers[i] = (rand() % 170) + 1;

       if(numbers[i] % 2 == 0) {

           cout << numbers[i] << endl;

       }

   }

}

Answer 1

thanks a lot. I believe the point of the assignment is to use pointers. Your way allows me to return the array as an argument, while my way passes the array, I think?
