Enter a number from 1 to 3 to select product size:

When users select 0 on the Product SU menu, close the menu and create an object of datatype class SU2022ProductSU_yourLastName to pass the arrayUnit and the arrayPrice as parameters

The transaction is created in the form of 4 digits: 0001, 0002, 0010, 0011, etc.

Use the object to access the method getTotal() of the datatype class to get and display the total charge of the order and display the message to ask and read the pay amount

Use the object to access the method printReceipt() of the datatype class to pass the transaction number and the pay amount as parameters to print out the receipt.

Open file daySale_06012022.txt to write.

Use the object to access the method toFile() to have the line to write this line to the file. Close file.

TASK2: REPORT DAY SALE PRODUCTS

-Display message and read from the keyboard for the file name that stored all the transactions sold for one day that are written from task 1. The file name in the format daySale_MMddyyyy.txt

-You can split the file name to get MMddyyyy then create the day of the report: MM/dd/yyy

-create one array size 3 to store 3 totals of units of 3 sizes that read all lines in file, for example, arrayTotalUnits

-open file with entered file name to read

-if the file exists, create while loop to read file until end of file

*For each line, split information in to 4 pieces

For example:

0001 20 10 12 20 is the number of small size, 10 is the number of medium size, 12 is the number of large size

-Add up number of small size to arrayTotalUnits [0], number of medium size to arrayTotalUnits[1], and number of large size to arrayTotalUnits[2]
