1) Create a file called "sample-cars.txt" in the project folder. Edit the
   file & add the following car names:

   Tesla
   Audi
   BMW
   Electra
   Cadillac
   Infiniti
   Nissan

   Write a program to read the file & print it out.


2) Extend the leap year program from last class by asking whether the
   user would like to save that information. If the user agrees,
   save output to a file named "leap-year.txt" after displaying it.
   Try to maintain the same formatted output in the text file.

   Demo:
   =====
   > Start year: 1900
   > End year:   2100
   > Save information? (y/n): y
