Transcribed Image Text:Practice question 1 (using python program)
Construct a FLOWCHART for a Point-of-Sales (POS) system that takes in customers
purchases by registering each of the products he/she brought forward to the counter for
payment. For each of the product codes entered, the system is to validate if it is a valid
code and display an error message "Invalid product code" if it is not. The cashier will
need to enter a valid code before the system proceeds to display the description of the
product, price of the product and prompt for the entry of the quantity of similar items
purchased. An error message "Invalid quantity entered" is displayed if the entered value
is not of the type “Integer". The entry of the product code and quantity into the system
will continue until a sentinel of "Q" is reached for the code. The system computes and
outputs the following information.
Total purchase amount
Rounding adjustment to the nearest 5 cents
• Total amount to pay
