Question
Need help with c++ program.
Write a program that stores stock symbols into dynamic arrays. The user will enter as many stocks as he/she wishes. The program should display the list of stocks after each one is entered. Sort stocks in alphabetical order. After that, use the program as a starting point for a menu-based program. The menu-based program should include these options:
1. Add a new stock.
Include room for the stock symbol, the name of the stock, and the current price.
2. Edit a stock.
Provide the ability to locate a stock based on its respective symbol and change the current price.
3. Delete a stock.
Offer the user the opportunity to enter a stock symbol and, if found, to delete the stock. If the particular stock symbol is not found, simply display an informative message to the user.
4. Display all stocks.
Display a list of all the current stocks stored in the array.
Explanation / Answer
In my early days I did prepare a code for Inventory management system for stock management .I think this will help you out the best way.
You can do perform any of the following operation on the basis of requirement:
1) Add item
2) Display stock
3) Search item
4) Update item information
5) Delete item information
6) Analysis of stock
Here I have used external file where all the operations would be done .
