Use arrays to track number of items sold for three inventory items from your food kiosk. Each of the three items has a number sold per day for one week. Program needs to track all the items sold, determine the average daily number sold, and determine the highest and lowest amount sold of any inventory item on a single day. For EXTRA CREDIT, the program also determines which inventory item had the most number of days with the highest number sold.

Step 1. Declare global constants: The number of inventory items (value = 3) The number of days (value = 7)

In main, declare a one-dimensional string array that will hold the three inventory items. Use the three inventory items from the food kiosk (sandwiches, french fries and beverage; platters are not an individual item for inventory purposes).

In main, declare a two-dimensional array that will hold the number of items sold for each item for each day. NOTE: Be sure to use the test data from Step 3 below. Call a function to display the program title, copyright notice and program introduction.

Step 2. Fill the arrays: Declare the two arrays (one-dimensional for the three items and two-dimensional for amount sold), initialize the arrays with the data to be used in the project. Use the test data below (see Step 3).

Step 3) Create a function that prints the contents of the two arrays in this format:

Name	day 1	day 2	day 3	day 4	day 5	day 6	day 7
Sandwiches	72	71	70	71	69	67	75
french fries	69	72	64	72	74	66	71
beverages	68	74	73	67	72	70	65

In the function heading, declare both arrays as constant arrays. Format as closely as possible, but don't obsess too much over perfection. The numbers must line up under the days, but they do not need to be exactly in the middle.

Step 4. Create a function that calculates and displays the average number of items sold over the seven days. In that function, display the averages with to one decimal place of precision. Report the results in the following format:

Name	Average sold
sandwiches	(report the results)
french fries	etc.
beverages	etc.

In the function heading, declare both arrays as constant arrays.

Step 5. Create a function that determines the one item that sold the lowest amount on a given day. Output the results in that function using the following format:

Item [item number] sold the lowest amount [value] on Day # [value of day].

In the function heading, declare both arrays as constant arrays. Place the inventory item name in the output above.

Step 6. Create a function that determines the one item that sold the most on a given day. Output the results in that function using the following format:

Item [item number] sold the lowest amount [value] on Day # [value of day].

In the function heading, declare both arrays as constant arrays. Place the inventory item name in the output above.

Step 7. Create a function that displays the item that sold the most over the most number of days. Output the results in that function using the following format:

Item [item number] had the most number of days with the highest sales, [number of days] days.

In the function heading, declare both arrays as constant arrays.

Notes: ? Use the test data and formatting as required above for the screenshot. ? Use good documentation the constants, variables, functions. ? Use variables and function names that are clear and self-explanatory. ? Pass the arrays as constants where appropriate. ? Use good spacing in both the code and the output.
