Converting array to vector

supernoob (49)
I'm supposed to modify a code from array to vectors.
But the vector one won't work and it says undefined reference to.

The original code:

#include <iostream>
using namespace std;// Function Prototype
bool testPIN(const int [], const int [], int);
int main ()
{const int NUM_DIGITS = 7; 
int pin1[NUM_DIGITS] = {2, 4, 1, 8, 7, 9, 0};
int pin2[NUM_DIGITS] = {2, 4, 6, 8, 7, 9, 0}; 
int pin3[NUM_DIGITS] = {1, 2, 3, 4, 5, 6, 7};
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";return 0;}

undefined reference to 'testPIN(std::vector<int, std::allocator<int> >&, std::vector<int, std::allocator<int> >&)'

undefined reference is on line 53 the ( int size )

HINT line 9 needs to be changed

HINT HINT you need to declare your ( int size ) on line 9

damn i didn't notice the int size it's not supposed to be there.
thanks a lot!
