24.2.1.Use the fill_n algorithms: Fill 3 more positions with Y's

#include <iostream>

#include <cassert>

#include <algorithm>

#include <vector>

#include <string>

using namespace std;



int main()

{

  string s("Hello there");

  vector<char> vector1(s.begin(), s.end());





  fill_n(vector1.begin() + 5, 3, 'Y');



  vector<char>::iterator pos;



  for (pos=vector1.begin(); pos!=vector1.end(); ++pos) {

        cout << *pos << ' ';

  }





  return 0;

24.2.fill_n
	24.2.1.	Use the fill_n algorithms: Fill 3 more positions with Y's
	24.2.2.	Use std::fill_n to fill the first five elements of chars with 'A'
	24.2.3.	Use fill_n function to insert 'hello' nine times
