#include <iostream>
using namespace std;

const int ARRAY_SIZE = 5;

bool valid2(const int list1[]);
void fillArray(int list1[], int ARRAY_SIZE);
void printArray(const int list1[], int ARRAY_SIZE );

int main()
{   
int list1[ARRAY_SIZE];
  bool found;


cout << "enter a number" << endl;

     fillArray(list1, ARRAY_SIZE);

    printArray(list1, ARRAY_SIZE);
     cout << endl;

      valid2(list1);

  if (!found)
  cout << "repeat number" <<endl;
  else 
  cout << " " <<endl;
