Source Code

#include "stdafx.h"
#include <vector>
#include <iostream>
#include <algorithm>
#include <functional>
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
  
    cout << "Enter your 10 numbers";
    vector<int> numbers(10);
    for(size_t n = 0; n < numbers.size(); ++n)
       cin >> numbers[n];

    nth_element(numbers.begin(), numbers.begin() + 2, numbers.end(),//we have used "#include <algorithm>" for the function nth_element
                greater<int>());//we have used "#include <functional>" for the function greater<int>()

    cout << "Third Largest number is " << numbers[2] << '\n';
 system("PAUSE");

 return 0;
}
