std::find and std::find_if for finding information in vectors

Here is a simple program that demonstrates how to use find and find_if with vectors.

//Program tested on Microsoft Visual Studio 2008 - Zahid Ghadialy
#include <iostream>
#include <vector>
#include <algorithm> //needed for std::find

using namespace std;

bool isOdd(int i) 
{
  return ((i%2)==1);
}

int main()
{
  vector<int> v1;
  v1.push_back(88);
  v1.push_back(99);
  v1.push_back(22);
  v1.push_back(33);
  v1.push_back(44);
  v1.push_back(55);
  v1.push_back(66);
  v1.push_back(77);

  //Demonstrating Find - Find number 55 and its position, if present
  vector<int>::const_iterator it = find(v1.begin(), v1.end(), 55);
  if(it != v1.end())
  {
    cout<<"Found: "<<*it<<endl;
    cout<<"Position = "<<it - v1.begin() + 1<<endl;
  }
  else
  {
    cout<<"Not Found"<<endl;
    cout<<"Position = -1"<<endl;
  }

  //Demonstrating Find IF - Find the first Odd number and its position
  it = find_if(v1.begin(), v1.end(), isOdd);
  if(it != v1.end())
  {
    cout<<"Found: "<<*it<<endl;
    cout<<"Position = "<<it - v1.begin() + 1<<endl;
  }
  else
  {
    cout<<"No Odd Numbers Found"<<endl;
    cout<<"Position = -1"<<endl;
  }

  return 0;
}

The output is as follows:
