• Problem 1: (85 points)

  Write the following functions:

  • Function productDiv5 that has one parameter - the number of input integers. The function inputs integers, and finds and RETURNs the product of the inputs that are divisible by 5. If there are NO such inputs, the function returns 0. USE LOOP FOR in this function.
  • Function aveLastOdd that has NO parameters. The function inputs the series of positive integers. The first zero or negative terminates the input. The function finds and RETURNs the average of the ODD LAST DIGITS of the input numbers. If there are no numbers with odd last digits, the function returns -1. In this function you can only use LOOP WHILE.
  • Function menu that has one parameter - choice. The function performs the following: if the choice is 1, user is asked to enter the number of inputs and the function productDiv5 is called. If the choice is 2, function aveLastOdd is called. For all other choices, function outputs error message.
  • Write main function that reads one integer - user's choice and call function menu.

• Problem 2: (15 points)

  The winter sale in some store has the following rules: if the original price of the item is 50 dollars or less, the item has 20% discount, otherwise, the item has 50% discount.

  Write the program randomly generates the number of items in the store and original price for each item. The program stores the prices in the list. We will assume that prices are INTEGERS between 25 and 75.

  The program creates a new list of discounted prices for all items.

  The program finds:

  1. average original price
  2. average discounted price
  3. number of items that received 20% discount
  4. number of items that received 50% discount
