Write a function whose job is to input #'s, non-# to quit, recover from the input failure by calling recover(), and tell main some statistics about the numbers read.

. unsigned readA();

Read unsigned #'s, non-# to quit, recover, return the sum of all #'s read.

For example, if main says

            cout <<"The total is " <

and if the user types

            2 4 6 8 blah

then readA will read the numbers 2, 4, 6, 8, keeping track of the total of the numbers read, readA will then choke on the "blah", readA will then, call recover() so that cin recovers from the input failure and moves past the "blah", readA will then return the 20, then main will resume the cout statement so that it outputs

            The total is 20
