2 Work Log and Summary: (Use the Work log template) Begin with a blank copy of the Work log template and log your hours for the design and implementation phase of program 5. Remember to write your reflection of the experience once you complete the program. Design, test and implement the following C++ program: You are working for the Igloo Ice Cream Parlor and given the task of creating a menu driven program to assist in creating customer receipts. The menu should contain the following options: 1. Start a new customer order clear the order data (give a second chance to not clear data) This will clear all the running totals (set them to zero). 2. Ordering Ice Cream Sundaes should prompt the user for the number of ice cream sundaes. 3. Ordering Ice Cream Cones should prompt the user for the number of ice cream cones. 4. Ordering Milkshakes should prompt the user for the number of milkshakes. 5. Generate the customer receipt for their order. This should be appended to any other orders already written to the file. The receipt output file should be named: receipt.rpt 6. Exit the program - Make sure to exit the program gracefully through the return 0 at the bottom of main( ). Write a menu driven program that will provide the user with the 6 menu options indicated above. The user should be able to make a selection, execute the code for that selection, and then return to the menu until option (6) Exit is selected. If the end-user enters an invalid menu option, print an error message and redisplay the menu, getting a new selection. When an option from the menu is selected your program should call a function to do the selection processing. If the end-user enters a qty that is less than 0 or enters character data, print an error message and prompt the user for a new value. Keep a running total of how many of each item is ordered. When the option to start a new order is selected, ask the user if they are sure they want to clear the order. If the user answers y or Y then clear the running totals for all ice cream products. Any other input should not clear the running totals. When the end-user selects to create a receipt, write a summary of the items ordered (don't print items that have a count of zero), calculate the subtotal, tax (using 6%), and the total order to an output file named receipt.rpt (use append mode of opening the file so each order is appended to the end of the file). If the entire order is zero, do not generate a summary; simply write the line: No order was placed. Each receipt written should have a delimiter a new line, line of *, and a new line. The Example Run shows the user screen experience. Be sure that each user input is followed by a new line. This will allow the redirected input/output used for testing to be readable.

3 Suggestions for developing a working solution (these match the stages of credit): (See the stages of credit at the end of this document) Design and implement p5a.cpp to get a valid number of ice cream sundaes from the user and update a running total. Add a loop that executes this code 5 times. Make sure to test all the valid and invalid data to be sure it works. Print the running total at the end of the program. (Stage 1) Design and implement p5b.cpp (modifying p5a.cpp) that has a 2-item menu that executes 5 times. If the user selects 2 from the menu then process the number of ice cream sundaes, if the user selects 3 from the menu then process the number of ice cream cones. Maintain two running totals, one for ice cream sundaes and one for ice cream cones. Make sure to test all the valid and invalid data to be sure it works. Print the running totals at the end of the program. Design and implement p5c.cpp (modifying p5b.cpp) that has a 3-item menu that executes 10 times.. If the user selects 2 from the menu then process the number of ice cream sundaes, if the user selects 3 from the menu then process the number of ice cream cones, and if the user selects 4 from the menu then process the number of milkshakes. Maintain three running totals, one for ice cream sundaes, one for ice cream cones, and one for milkshakes. Make sure to test all the valid and invalid data to be sure it works. Print the running totals at the end of the program. (Stage 2) Design and implement p5d.cpp (modifying p5c.cpp) that has a 4-item menu that executes 10 times. If the user selects 1 from the menu then clear the running totals. if the user selects 2 from the menu then process the number of ice cream sundaes, if the user selects 3 from the menu then process the number of ice cream cones, and if the user selects 4 from the menu then process the number of milkshakes. Maintain three running totals, one for ice cream sundaes, one for ice cream cones, and one for milkshakes. Make sure to test all the valid and invalid data to be sure it works. Print the running totals at the end of the program. (Stage 3) Design and implement p5e.cpp (modifying p5d.cpp) that has a 4-item menu that executes 10 times. The menu remains the same as in p5d.cpp. When the program ends print the running totals to the screen and write the customer receipt to receipt.rpt. Make sure to test this with totals that are zero! (Stage 4) Design and implement p5.cpp (modifying p5e.cpp). Return to the program specifications and complete the implementation as directed. (Stage 5) Updated: 12/3/2018 3

4 Input Data: You will be running your program using redirection instead of typing in the input. I am providing the canned input files that you will use. Copy them from my p5 directory and into your directory: cp ~zimmer/csci130/191/p5/p5_*.in. Stage of Credit Input files to use Commands to execute p5a.exe < p5_stage1.in > p5.out Stage 1 p5_stage1.in * print p5.out Stage 2 Stage 3 p5_stage2.in p5_stage3.in p5c.exe < p5_stage2.in > p5.out * print p5.out p5d.exe < p5_stage3.in > p5.out * print p5.out Stage 4 p5_stage4a.in p5_stage4b.in p5_stage4c.in rm receipt.rpt p5e.exe < p5_stage4a.in > p5a.out p5e.exe < p5_stage4b.in > p5b.out p5e.exe < p5_stage4c.in > p5c.out * print p5a.out, p5b.out, p5c.out * print receipt.rpt Stage 5 p5_stage5.in rm receipt.rpt p5.exe < p5_stage5.in > p5.out * print p5.out * print receipt.rpt Updated: 12/3/2018 4
