Re: exception on string (out_of_range)

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';
 }
}
