A coffee bar, Griff's Glorious Grounds, wants a program to print a customer's bill.
The program should display a welcome message and then input the customer's name, the total for the coffees purchased, and tip if any.
Coffee ranges from $3 (Regular), $5 (Large), and $10 (Specialty)
The program is to calculate the total price with a 13% tax applied; then calculate a tip, which can be either 15, 20, or 25%.
Produce output showing the price before tax, how much tax will be added, and the total amount due with all tips applied.
