Question
using the source codes at the bottom of the page, turn all the different files into a single file program while using the following instructions.
Serendipity Booksellers Software Development Project— Part 6: A Problem-Solving Exercise
1. Function Name Change
It is now time to make one program from the separate files you have created. Perform the following function name changes:
Change the name of function main in cashier.cpp to cashier.
Change the name of function main in invmenu.cpp to invMenu.
Change the name of function main in bookinfo.cpp to bookInfo.
Change the name of function main in reports.cpp to reports.
Save each file after you have changed the name of its function main.
2. Development Strategy
You must now decide if you are going to develop the project as a multi-file program or simply merge all the functions listed above into the mainmenu.cpp file. (See Appendix K: Multi-Source File Programs)
Multi-File Program
If you decide on the multi-file program approach, follow the directions in your compiler manuals to create a project or “make files” for this program. The files that are part of the project are mainmenu.cpp, cashier.cpp, invmenu.cpp, bookinfo.cpp, and reports.cpp. mainmenu.cpp will be the main file.
Single-File Program
If you decide to merge the functions of the project into one file, simply use the cut and paste feature of your editor to perform the following:
Copy the cashier function in cashier.cpp and paste it into the mainmenu.cpp file.
Copy the invMenu function in invmenu.cpp and paste it into the mainmenu.cpp file.
Copy the bookInfo function in bookinfo.cpp and paste it into the mainmenu.cpp file.
Copy the reports function in reports.cpp and paste it into the mainmenu.cpp file.
3. Header File Creation
Multi-File Program
If you are developing a multi-file program, create the following header files:
cashier.h: This file should contain a function prototype for the cashier function. Place an #include directive in cashier.cpp that includes cashier.h.
invmenu.h: This file should contain a function prototype for the invMenu function. Place an #include directive in invmenu.cpp that includes invmenu.h.
bookinfo.h: This file should contain a function prototype for the bookInfo function. Place an #include directive in bookinfo.cpp that includes bookinfo.h.
reports.h: This file should contain a function prototype for the reports function. Place an #include directive in reports.cpp that includes reports.h.
Single-File Program
If you are developing a single-file program, create a header file named mainmenu.h. It should contain function prototypes for the following functions:
cashier invMenu bookInfo reports
Place an #include directive in mainmenu.cpp that includes mainmenu.h.
4. Switch Modification in main
Modify the switch statement in function main (of mainmenu.cpp) so that instead of displaying the number entered by the user, it calls
function cashier if the user selects 1, function invMenu if the user selects 2, function reports if the user selects 3.
5. Inventory Database Stub Functions
Add stub functions that will later perform operations selected from the Inventory
Database Menu. The functions are
void lookUpBook(). This function should display the message “You selected Look Up Book.”
void addBook(). This function should display the message “You selected Add Book.”
void editBook(). This function should display the message “You selected Edit Book.”
void deleteBook(). This function should display the message “You selected Delete Book.”
Multi-File Program
If you are developing a multi-file program, add the functions above to the invmenu.cpp file. Add function prototypes for each function to invmenu.h.
Single-File Program
If you are developing a single-file program, add the functions above to the mainmenu.cpp file. Add function prototypes for each function to the mainmenu.h file.
6. Switch Modification in invMenu
Modify the switch statement in function invMenu so that instead of
displaying the number entered by the user, it calls
function lookUpBook if the user selects 1, function addBook if the user selects 2, function editBook if the user selects 3, function deleteBook if the user selects 4.
7. Report Stub Functions
Add stub functions that will later perform operations selected from the Reports Menu. The functions are
void repListing(). This function should display the message “You selected Inventory Listing.”
void repWholesale(). This function should display the message “You selected Inventory Wholesale Value.”
void repRetail(). This function should display the message “You selected Inventory Retail Value.”
void repQty(). This function should display the message “You selected Listing By Quantity.”
void repCost(). This function should display the message “You selected Listing By Cost.”
void repAge(). This function should display the message “You selected Listing By Age.”
Multi-File Program
If you are developing a multi-file program, add the functions above to the reports.cpp file. Add function prototypes for each function to reports.h.
Single-File Program
If you are developing a single-file program, add the functions above to the mainmenu.cpp file. Add function prototypes for each function to the mainmenu.h file.
8. Switch Modification in reports
Modify the switch statement in function reports so that instead of
displaying the number entered by the user, it calls
function repListing if the user selects 1, function repWholesale if the user selects 2, function repRetail if the user selects 3, function repQty if the user selects 4, function repCost if the user selects 5, function repAge if the user selects 6.
