Question
(the program is written using arrays. You have to change this program and modify the program to use vectors instead of arrays.)
Modify the following program so pin1, pin2, and pin3 a
re vectors instead of arrays
// 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(const int [], const 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 v
alues.
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 elem
ents are
//
different from pin1.
if (testPIN(pin1, pin2, NUM_DIGITS))
cout << "ERROR: pin1 and pin2 report to be the same. ";
else
cout << "SUCCESS: pin1 and pin2 are different. ";
if (testPIN(pin1, pin3, NUM_DIGITS))
cout << "ERROR: pin1 and pin3 report to be the same. ";
else
cout << "SUCCESS: pin1 and pin3 are different. ";
if (testPIN(pin1, pin1, NUM_DIGITS))
cout << "SUCCESS: pin1 and pin1 report to be the same.
";
else
cout << "ERROR: pin1 and pin1 report to be different. ";
return 0;
}

bool testPIN(const vector<int>& custPIN, const vector<int>& databasePIN, int size)
{
if (custPIN == databasePIN)
return true;
else
return false;
}
Output:
SUCCESS: pin1 and pin2 are different.
SUCCESS: pin1 and pin3 are different.
SUCCESS: pin1 and pin1 report to be the same.
