Task: Arrays and Structs
Overview
In this task you will continue to work on the knight database to help Camelot keep track of all of their knights. We can now add a kingdom struct to help work with and manage all of the knights in the kingdom.
Instructions
To get started:
1. Watch this week's video on updating the Kingdom Database code with additional types and dynamic arrays, and make the changes shown there. See the Update Kingdom Database video for details.
Changes include:
A Kingdom struct with a vector of knights
An add_knight procedure to add a knight into the Kingdom
A write_kingdom procedure to output the details of the Kingdom and its knights A delete_knight procedure to delete a knight from the kingdom
2. Now make the following additional changes:
1. Add a select knight function.
Implement int select_knight(const kingdom_data &kingdom)
This will return the index of a knight in the array.
It will show the user a list of all of the knights (with index numbers next to them, starting at 1)
The user is then asked to select a knight by entering their index (with 0 being no knight) The prompt should loop until the user selects a valid option.
The function then returns the value the user entered - 1. So selecting no knight will return the value -1, the first knight will be 0, and so on.
2. Add a menu to allow the user to choose between the different system actions: adding knights, deleting knights, displaying details
Adding will use add knight
Deleting will need to be a new procedure - it can call select_knight and if the result is not -1, it can then use this in a call to delete_knight
Displaying will show the kingdom data
3. Add items to each knight.
Add a dynamic array of strings called items ( Knight.) to the
Change update_knight to include the ability to add an item. When this is selected, have the user enter the details of a new item and add this to the knight's current items.
Change write_knight to output the number of items the knight is carrying.
4. Add a query knight option to the main menu. This will allow the user to output the details of a single knight.
Implement void query_knight(const kingdom_data &kingdom) Select a knight to query - Do you have a function for this already? Use write_knight to display their general details
Then list all of their items with an appropriate header
3. Answer the questions from the resources associated with this task.
4. Submit your program code along with a screenshot of it working.
