$\}$Initialization:

Define constants for menu choices $($CHOICE$\_1,$ CHOICE$\_2,$ CHOICE$\_3,$

DONE$\_$CHOICE$).$

Declare variables for user input $($choice and itemName$).$

Create vectors $($walmartItems$,$ hometownMarketItems.

samsclubitems$)$ to store items for each store.

Menu Loop:

Use a do$-$while loop to display the menu and get the user's choice.

Validate the user's choice to ensure it is within the menu options.

Item Entry Loop:

If the user hasn't chosen to exit $($choice $!=$ DONE$\_$CHOICE$),$ enter a

loop to get items for the selected store.

Use a loop to get five items from the user.

Based on the user's choice, store each item in the corresponding

vector $($walmartItems$,$ hometownMarketItems, samsclubItems$).$

Display Items:

After the user is done, sort each vector in alphabetical order.

Display the sorted items for each store using a loop.

File Output:

Open an output file $($grocery$\_$list.txt$).$

Write the sorted items for each store to the file.

Close the output file.

Conclusion:

Display a message indicating that the data has been written to the

file.
