Need to convert arrays into vectors

[d15tur83d]

This is the program I have so far and I need to change it from arrays into vectors
// This program is a driver that tests a function comparing the
// contents of two int arrays.
#include <iostream>
using namespace std;

// Function Prototype
bool testPIN(int [], int [], int);

int main ()
{
const int NUM_DIGITS = 7; // Number of digits in a PIN

int pin1[NUM_DIGITS] = {2, 4, 1, 8, 7, 9, 0}; // Base set of values.
int pin2[NUM_DIGITS] = {2, 4, 6, 8, 7, 9, 0}; // Only 1 element is different from pin1.
int pin3[NUM_DIGITS] = {1, 2, 3, 4, 5, 6, 7}; // All elements are different from pin1.

if (testPIN(pin1, pin2, NUM_DIGITS))
cout << "ERROR: pin1 and pin2 report to be the same.\n";
else
cout << "SUCCESS: pin1 and pin2 are different.\n";

if (testPIN(pin1, pin3, NUM_DIGITS))
cout << "ERROR: pin1 and pin3 report to be the same.\n";
else
cout << "SUCCESS: pin1 and pin3 are different.\n";

if (testPIN(pin1, pin1, NUM_DIGITS))
cout << "SUCCESS: pin1 and pin1 report to be the same.\n";
else
cout << "ERROR: pin1 and pin1 report to be different.\n";
system("pause");
return 0;
}

//******************************************************************
// The following function accepts two int arrays. The arrays are *
// compared. If they contain the same values, true is returned. *
// If the contain different values, false is returned. *
//******************************************************************

bool testPIN(int custPIN[], int databasePIN[], int size)
{
for (int index = 0; index < size; index++)
{
if (custPIN[index] != databasePIN[index])
return false; // We've found two different values.
}
return true; // If we make it this far, the values are the same.
}

Unfortunately, the { } initialization doesn't work with vectors. There is already a std algorithm that does what you need. Your testPIN function isn't needed.
http://cplusplus.com/reference/algorithm/equal/

It even shows how to use 1 array using aggregate initialization to subsequently construct a vector although it is unfortunate that you have to do that. Since this program is building arrays to test your testPIN function that reinvents the wheel the rest is a moot point.
