15.19.1.search a sub string

#include <iostream>

#include <string>

using namespace std;



int main()

{

  int i;

  string s1 ="this is a test.";

  string s2;



  i = s1.find("is");

  if(i!=string::npos) {

    cout << "Match found at " << i << endl;

    cout << "Remaining string is:\n";

    s2.assign(s1, i, s1.size());

    cout << s2;

  }

  cout << "\n\n";





  return 0;

}

Match found at 2
Remaining string is:
is is a test.
