try/catch

[daviddoria]

This doesn't seem to behave as I would expect (as it does in matlab, for example). I want to execute a command, but give some readable output instead of the often very messy auto-generated error (index out of range or something).

try
{
  MyFunction(1,2);
}
catch(char* str)
{
  cout << "There was a problem." << endl;
}

Is that now how you do this in c++?

Thanks,

Dave

Your syntax is correct, but you are probably not catching the correct thing. Usually the standard error is a descendant of runtime_error in <stdexcept>.

Take a read through http://www.parashift.com/c++-faq-lite/exceptions.html
and check 17.6 and 17.7.

Hope this helps.

ah - i see, i wasn't throwing anything, so clearly it was not being caught! Thanks for the link.
