How do I convert this array to a vector?

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};

std::vector defines a constructor that takes in two InputIterators and a default allocator with

template <class InputIterator>
     vector (InputIterator first, InputIterator last,
             const allocator_type& alloc = allocator_type());

So you can just create a vector from an array like so,

std::vector<int> vec(pin1, pin1 + NUM_DIGITS);
