• You will have a menu option to create a taxpayer. It should be the first one in the menu.
  The menu should look as follows:
  1. create a taxpayer
  2. modify income of a given taxpayer
  3. calculate taxes to pay for a given taxpayer
  4. print all the taxpayers
• For options 2 and 3, the search for the taxpayer should be done by taxpayer number.
  Each taxpayer should be stored in the array position corresponding to his/her taxpayer number
  Taxpayer numbers should be betweek 1 and 99,999. (yes, we will "waste" position zero)
  Aside from these changes, all the requirements and policies applicable to assignment 3 still apply to this homework.

Tip: The SSN should be unique. Before creating a taxpayer object, read the corresponding SSN. Verify that it is not part of your array. If it is send a message letting the user know that it is a duplicate SSN. If it is not part of your array, then collect the remaining information, validate it, create the taxpayer and add it to your array.
