To generate the receipt list based on some input will need to pass an input file path, e.g. given an input1 file with the following content:
Input 1:
2 book at 12.49
1 music CD at 14.99
1 chocolate bar at 0.85
Run execute.rb passing the file path as an argument.
For example:
$ ruby execute.rb input1 INT
Input 1:
2 book at 12.49
1 music CD at 14.99
1 chocolate bar at 0.85
-----------------
Output 1:

1 music CD: 16.49
1 chocolate bar: 0.85
Sales Taxes: 1.50
Total: 42.32
