electronic items require VAT payment of 15 percentage of their prices. There are packed and
lose food. The lose food is measured in weights. User specifies the weight amount or the
quantity in his selection of items depending on its type. The price is computed as the product
of the price per item or the price per weight and the weight or quantity are given by the user.

Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tellsthe ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not.. Test your application with the following ticket numbers: - 123454; is a valid ticket number - 147103; is a valid ticket number -…arrow_forward
