stl vector iteration code example

Example 1: c++ vector iterator

#include <iostream>
#include <vector>
using namespace std;

vector<int> myvector;

for (vector<int>::iterator it = myvector.begin();
     it != myvector.end();
     ++it)
   cout << ' ' << *it;
cout << '\n';

Example 2: iterate over vector in c++
