Description

Now let's consider a case where you need a lot of coffee. Maybe, for example, you’re hosting a party with a lot of guests. The program should calculate how much water, coffee, and milk are necessary to make the specified amount of coffee. One cup of coffee made on this coffee machine contains 200 ml of water, 50 ml of milk, and 15 g of coffee beans.

The user should input the amount of coffee he needs, in cups, for all the guests.

Of course, all this coffee is not needed right now, so at this stage, the coffee machine doesn’t actually make any coffee.
