How can I can understand my func throw exception or not in if statement?

You basically can't. You can catch the exception and then handle the not-found case there but that's cumbersome. Your design could be improved if you did something other than throwing an exception. STL returns an end-iterator, as an example. If you're returning index of the element, you can return -1 or size of the array for instance. The main problem is that you're using exceptions in a places they are not meant to be used.

My suggestion would be to use std::find and not invent the wheel anew.
