===== Assignment C - Button for diggit 1 - 5' =====
  * C01: Create the buttons 1 to 4 (that shall suffice for our purpose)  
  * C02: When clicking on one of them the content will be saved in the variable **diggit1** with the corresponding number 1-4, meaning when clicking the 1, the variable diggit will be set with 1.

===== Assignment D - Button for diggit 2 - 3' =====
  * D01: Create the second set of buttons 1 to 4 to set the second diggit. (4 of them shall suffice for our purpose)  
  * D02: When clicking on one of them the content will be saved in the variable **diggit2**

===== Assignment E: Implementation of the calculation - 5'  =====
  * E01: To execute our addition-operation we finally need a button **Operator**-button.
  * E02: Clicking this operator-Button adds diggit1 to diggit2 and displays the result (result = diggit1 + diggit2)

===== Assignment F: Reset button - 5'  =====
  * F01: Create finally a **reset**-button which sets all value to the initial ones.
  * F02: Meaning clicking on the reset-button uses: result=0, diggit1=0, diggit2=0
