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';
}
}

that mean it was tested success in some platform(vc++ in xp), so
please help, thanks a lot in advance, Eric
