Hello. I have an assignment that asks me to create a program that asks a customer of a store to type in their name, and an ammount of money they spent. Then the program calculates a dicount they get according to the amount of money they spend. And print the discount to the screen. But it says that the data should be read from a file, not from the keyboard. I don't understand what it means about being "read from a file, not the keyboard".
