* CSIT 210 - Project 1
* Overview: Gets franchise name and converts it to all uppercase, then displays a total of all  sales with a 9 digit confirmation code

*            childTotal, mediumTotal, largeTotal, extraLargeTotal, finalTotal, confirmation_code, franchise
* Plan: 
* 1. Gets the franchise name as a String 
* 2. Gets the number of child, medium large and extra large sizes sold as integers
* 3. Converts the franchise name to all uppercase
