  Vektor elementlarinni iterator bilan ekranga chiqarishni ko‘ramiz:
  
• 
  
  vector test;
  
• 
  
  string buffer = "";
  
• 
  
  //elementlarni kiritilsh
  
• 
  
  do {
  
• 
  
  getline(cin, buffer);
  
• 
  
  if (buffer.size() > 0) test.push_back(buffer);
  
• 
  
  } while (buffer != "");
  
• 
  
  vector::iterator cur;
  
• 
  
  for (cur=test.begin();cur
  
• 
  
  cout<<*cur<

  2ta uzunligi teng bo‘lgan vektorni siklsiz solishtirish mumkin. Bunda ularning mos elementlari qiymatlari solishtiriladi. Masalan:
  
• 
  
  #include
  
• 
  
  #include
  
• 
  
  using namespace std;
  
• 
  
  int main()
  
• 
  
  {
  
• 
  
  vector array1(3);
  
• 
  
  array1[0] = 4;
  
• 
  
  array1[1] = 2;
  
• 
  
  array1[2] = 1;
  
• 
  
  vector array2(3);
  
• 
  
  array2[0] = 4;
  
• 
  
  array2[1] = 2;
  
• 
  
  array2[2] = 1;
  
• 
  
  // vektorlarni solishtirish
  
• 
  
  if (array1 == array2) {
  
• 
  
  cout << "array1 == array2" << endl;
  
• 
  
  }
  
• 
  
  return 0;
  
• 
  
  }

  vector array1;
  
• 
  
  array1.insert(array1.end(), 4);
  
• 
  
  array1.insert(array1.end(), 3);
  
• 
  
  array1.insert(array1.end(), 1);
  
• 
  
  copy( array1.begin(), // vektor boshi iteratori
  
• 
  
  array1.end(), // vektor oxiri iteratori
  
• 
  
  ostream_iterator(cout," ") //chiqarish potoki iteratori
  
• 
  
  );

  return 0;
