to require the user to enter the same value twice in order 
to add that value to the total.

=begin  A big assumption I made for this code is that the number needing to be confirmed 
is the first number that the user attempts to input is the number needing to be confirmed
until it is confirmed.

Prompt user to confirm number. Continue to prompt until the user conrims.
Add the user input to the total each time they confirm the number
