Exception Handling

• If any of the functions in the try clause throw a logic_error, or call another function that throws such an exception, then the code in the catch clause executes immediately.

  while (more)
  {
     try 
     {
        code
     }
     catch (logic_error& e)
     {
        cout << "A logic error has occurred "
           << e.what() << "\n"
           << "Retry? (y/n)";
        string input;
        getline(cin, input);
        if (input == "n" more = false;
     }
  }
  

• The what member function of the locic_error class returns the string that was passed to the constructor of the error object in the throw statement.
