Uno sguardo alla guida ?

codice:
#include <iostream>
#include <cstdlib>
using namespace std;

void foo (int array[], unsigned int n);

main ()
{
	int arr[10];
	foo (arr, 10);
	
	for (unsigned int i = 0; i < 10; i++)
		cout << arr[i] << endl;

	cout << endl;
	return EXIT_SUCCESS;
}

void foo (int array[], unsigned int n)
	{
	srand((unsigned int) time(NULL));
	for (unsigned int i = 0; i < n; i++)
		{
		array[i] = rand() % 3 + 1;
		}
	}
