*                                                                                  *
* 1 Ask someone to enter the amount of integer values to be entered                *
*                                                                                  *

* 2.5 Say please enter a positive number for the amount of values to be entered    *
*	   and if the number they enter is positive go to step 3, if it is negative,    *
*     begin step 2.5 again															*
*                                                                                  *

*  4 Check if number is even or odd by seeing if the number has a remainder when   *
*                it is divided by 2                                                *

*         If number even                                                           *
*             Display Number entered is even                                       *
*                                                                                  *
