       that when you execute your sh file, it will produce the following:

     a - Append your name, current date and time to a NEW file called results.txt

         and ask for a correct second number.
     g - If the second number is NOT a zero, do the division, display all numbers of 
         this computation using labels, and add the same to the results.txt file.
