A procedure TwoParts() will input a sequence of real values, one at a time. The procedure will: • process the sequence in two parts • form a first total by adding the values until the first zero • form a second total by adding the values after the first zero until the second zero • output the average of the two totals, together with a suitable message. Values input in the first part are totalled using global variable TotalA and those input in the second part are totalled using global variable TotalB.
