C + + program code generation, generation, write C + + stock price
Guideline of assignment
Let us assume this is a investor who holds a portfolio of stocks. You need to design a C + + program to maintain and manage the stock price information of 7 days.
General Features and Functions
? Basic Features:the program should is able to
1) Store The Portfolio information into a 2-dimentional array (Nx8) of String type. The first column of the array for stock code, and the rest columns for 7-day prices. Declare the total number of stocks as a constant valued (i.e., N = ten), and initialize the array by setting cod E to the string "NULL" and prices 0. Below is a exemplar portfolio with 2 stocks.

0280031.2532.533.733.235.835.130.7

03700419.6422.3421.7429.2411.9412.6410.1

NULL0000000

NNULL0000000


NULL0000000

2) Add a new stock into the portfolio to an available place (Input:code and 7 prices). If No available space left (all rows is occupied), print the error message accordingly.
3) Retrieve a stock (Input:stock code). If found, display all 7 prices, and the lowest, highest, and average price.
4) Modify The price of a stock on a certain day (Input:stock code, day and new price)
Onote that only a-stock that exists in the portfolio can be changed.
5) Delete a stock (the whole record, including its prices; Input:stock code)
Onote that only a-stock that exists in the portfolio can be deleted.
6) Display the entire portfolio
7) Populate random values into the entire portfolio (for testing purpose)
Ostock code:a Random 4-digit in the range of 1000-4999
OPRICE:A double number between [0, +], in the format of, for example, 28.3. Note that it's saved as a string in the array

? Bonus Features
8) User input Validation:check If user input is valid and prompt if not (e.g., a valid price)
9) Feel free to add any other relevant features to your system
? Hints
-user interface and Features
Osee an exemplar interface as in the given sample code (SAMPLEUSERINTERFACE.CPP)
Ofor your reference, see a exemplar system coded by me, run the file ' PortfolioManager.exe ' to try my demo program. Note that other files in the same package is supporting library files that should is put in the same folder as the. exe F ile).
Ohowever, feel comfortable to design a interface that you prefer, either simplified or feature-richer.
