C++ Tutorial/vector/vector resize

force the vector to reallocate

<source lang="cpp">#include <algorithm>

1. include <iostream>
2. include <vector>

using namespace std; int main( ) {

  vector<int> v( 10, 66 );
  v[1] = 100;
  // get an iterator that points to the maximum
  vector<int>::iterator before_itr = max_element( v.begin(), v.end() );
  cout << "The maximum before resizing is " << *before_itr;
  // make the index of the maximum
  vector<int>::difference_type max_index = before_itr - v.begin();
  // force the vector to reallocate
  v.resize( v.capacity() + 1 );
