equal_range in C++

// C++ program to demonstrate the use of std::equal_range
#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
int main()
{
    vector<int> v = { 10, 10, 30, 30, 30, 100, 10,
                      300, 300, 70, 70, 80 };
  
    // Declaring an iterator to store the
    // return value of std::equal_range
    std::pair<std::vector<int>::iterator,
              std::vector<int>::iterator> ip;
  
    // Sorting the vector v
    sort(v.begin(), v.end());
    // v becomes 10 10 10 30 30 30 70 70 80 100 300 300
  
    // Using std::equal_range and comparing the elements
    // with 30
    ip = std::equal_range(v.begin(), v.begin() + 12, 30);
  
    // Displaying the subrange bounds
    cout << "30 is present in the sorted vector from index "
         << (ip.first - v.begin()) << " till "
         << (ip.second - v.begin());
  
    return 0;
