Exception...

In the attached code user is to enter two integers and get their sum.

It is supposed to throw exception:

-if the entry was more than two:
    2 4   <-- is correct
    2  3  7  <--not correct has three numbers

-if both not integer (float string, etc)

After giving the error, it is supposed to ask user to enter it again.

Thank you.
