Array of Structs Homework Help

Interactive Menu-driven Program Using Array of Structs

Write an interactive, menu-driven C++ program that uses an array of structs and separate functions to do the following:

1. Use a “do loop” or a “while loop” to display a menu with the following choices:

1 - Add Parts

2 - Sort Parts

3 - Display All Parts

4 - Display Parts to Reorder

5 - Display a Specific Part

6 - Exit

Exit the loop when menu option 6 is selected. Use a default

menu option to indicate an invalid menu option was entered.

Menu Functions

2. Create and call the following functions from the menu:

• addParts – Allows the user to enter and validate:

a. A numeric Part ID – between 1 and 1000

b. A part description (use array of characters)

c. A numeric wholesale price – between $1.00 and $1,000.00

d. A numeric retail price – between 10% and 200% greater than the wholesale price

e. A numeric quantity-on-hand – between 0 and 100

f. A numeric reorder point – between 1 and 50

• sortParts – Sort all part records in ascending or descending order by partID. Use a bubble sort.

• displayParts - Display all parts information for each part with one record on each line, include a screen title and column labels, and align all column content with the column labels. Include a total column and line to display the total retail value of all parts in the inventory.

• reorderParts - Display all parts information for parts with quantity on hand less than or equal to the reorder point. Display all parts information for each part with one record on each line, include a screen title and column labels, and align all column content with the column labels

• displaySpecificPart - Display all parts information for the specific part selected by the user.

Use an appropriate title for all screens and appropriate column headings. Display output horizontally for menu options 3, 4, and 5.
