16.18.2.Insert 10 duplicate value to vector

#include <iostream>

#include <vector>

using namespace std;



int main()

{

  vector<char> v(10);

  vector<char> v2;

  char str[] = "<Vector>";

  unsigned int i;



  for(i=0; i<10; i++) 

     v[i] = i + 'a';



  for(i=0; str[i]; i++) 

     v2.push_back(str[i]);

  

  cout << "Original contents of v:\n";

  for(i=0; i<v.size(); i++) 

      cout << v[i] << " ";

  cout << "\n\n";



  vector<char>::iterator p = v.begin();

  p += 2; // point to 3rd element



  v.insert(p, 10, 'X');



  // display contents after insertion

  cout << "Size after inserting X's = " << v.size() << endl;

  cout << "Contents after insert:\n";

  for(i=0; i<v.size(); i++) cout << v[i] << " ";

  cout << "\n\n";



  return 0;

}

Original contents of v:
a b c d e f g h i j

Size after inserting X's = 20
Contents after insert:
a b X X X X X X X X X X c d e f g h i j
