How to catch substr exception?

Question

I'm using substr for generating substring. How I can catch substr exception? For instance:

terminate called after throwing an instance of 'std::out_of_range'

Answer 1

Like this:

try
{
  /// use substr
}
catch( std::out_of_range& exception )
{
   // print out an error, and fail, or restart if appropriate.
}

Answer 2

try
{
    std::string sub = mystring.substr(10,1);
}
catch (std::out_of_range & ex)
{
    cout << "caught exception!" << endl;
}
