exception on string (out_of_range)

[eric <cneric12lin0 at gmail dot com>]

Dear Advanced C++ programers:

  from book (c++ cookbook), chapter 4, section 3: Storing Strings in a
Sequence
---------
#include <iostream>
#include <vector>
#include <exception>

using namespace std;

int main() {

  char carr[] = {'a', 'b', 'c', 'd', 'e'};

  cout << carr[100000] << '\n';    // Whoops, who knows what's going
                                   // to happen
  vector<char> v;
  v.push_back('a');
  v.push_back('b');
  v.push_back('c');
  v.push_back('d');
  v.push_back('e');

  try {
     cout << v.at(10000) << '\n';  // at checks bounds and throws
  } catch(out_of_range& e) {       // out_of_range if it's invalid
    cerr << e.what() << '\n';
  }
}
