Shall I use cerr

Question

Is it in good style do use cerr in situation described below?

try
    {
    cout << a + b;
    }
    catch(const IntException& e)
    {
        c         


        

Answer 1

Sure, it's good to use cerr there. You can redirect cerr differently from cout, sometimes that helps you to highlight problems that could go buried in a huge cout log file.
