Look at the 2 examples of Pseudocode supplied with this assignment

Choose as a program manager which pseudocode you would select to go ahead with as a project on for an entire group. So which pseudocode was clearest to a person who might not be a full time programmer or who might not know much about C++.

Justify your selection with one or two additional sentences explaining why you selected the one that you did and why you selected that one.

Pseudocode Example 1:

Global variables:

int BurgerPatties - total number of hamburger patties in inventory

int BurgerBuns - total number of hamburger buns

int Hotdogs - total number of hot dogs

int HotdogBuns - total number of hot dog buns

Assign Tax (5 divided by 100) times Total

Add Total plus Tax to CashRegister

Decrement Chili by (4 times quantity)

Else

Assign Total (5.00 times quantity)

Decrement BurgerBuns by quantity

Return Total plus Tax

End function

End function

My approach to this program is to use a large do-while loop, that records the users choice for

menu options. These menu options prompt the user again for the quantity of the selected item,

and tell the user is there is not enough of it in inventory. The total is calculated and added to the

cash register, and printed on the screen after the transaction. The loop checks the inventory for

each item, and warns the user if any of the items are getting low. At the end of the session, after

the user has entered q to quit, the amount of money that was made during the session is

printed on screen, with a detailed list of how many of each item was sold. I wrote three

functions: One for selling hamburgers, one for selling hotdogs, and one for printing the menu on

screen. Each of the inventory items has its own global variable.

Pseudocode Example 2:

Variables:

inventoryLeft (table of values containing inventory of each menu item)

menuItems (table containing strings of menu items)

itemOrdered

orderTotal

Constants:

itemPrices (table containing prices of menu items)

amtPerOrder (table containing amount of each item given every time its ordered)

twentyPercent (table containing values for twenty percent of initial inventory)

Program: RebelMenu

Display menuItems with corresponding numbers

Prompt user for the number corresponding to menu item ordered

Set itemOrdered to user entry

WHILE (itemOrdered does not equal -1)

IF (checkInventory() is true)

Subtract the amtPerOrder of the itemOrdered from the corresponding

inventoryLeft

IF (itemOrdered inventoryLeft is less than the corresponding twentyPercent)

Display Less than 20% inventory remains

END IF

Add the itemOrdereds price to orderTotal

Display orderTotal

END IF

ELSE

Display Not enough inventory, please order something else

END ELSE

Display menuItems with corresponding numbers

Prompt user for the number corresponding to menu item ordered (with -1 to quit and 10

to complete current customer order)

IF (itemOrdered equals 10)

Display orderTotal

Set orderTotal to 0

Display menuItems with corresponding numbers

Prompt user for the number corresponding to menu item ordered (with -1 to quit)

END IF

END WHILE

Function: checkInventory()

IF (itemOrdered inventoryLeft is less than corresponding amtPerOrder)

Replace corresponding menuItem with Sold Out

Return false

END IF

ELSE IF (itemOrdered inventoryLeft is equal to corresponding amtPerOrder)

Replace corresponding menuItem with Sold Out

Return true

END ELSE IF

ELSE

Return true

END ELSE

My approach is associating each menu item with a number, and using several vectors/arrays with

different attributes about the menu items to alter the inventory, get the order total, etc. All the

employee running the system would have to do is enter a number when the customer orders

something, making the program easy to use. When they want to finish an order, they enter 10,

and the order total is calculated. To close out at the end of the night, they enter -1. I use an

additional function to check if the inventory is less than necessary to fulfill the order, as well as

change the menu item to Sold out so next time the employee knows its sold out. Because the

chili is sold in different amounts, you cant guarantee anything more than 0 in inventory means

the order can be fulfilled.
