a program that allows you to view and edit the sales amounts for each month of the current year. Example COMMAND MENU add - Add sales for specified month view - View sales for specified month edit - Edit sales for specified month totals - View sales summary for year exit - Exit program
Monthly Sales
Example
Specifications
- The program should use a list to store the sales data for each month with the three-letter abbreviation for the month (Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, and Dec) as the key for each item.
- When the program starts, it should read the sales data inserted from the user.
- If the user edits the sales data, the program should edit the data (review slide 45 for calculate total function example).
- Has to be in c++
- Has to use ALL commands : add,edit,exit,totals, and view
- If the user selects total, the program should calculate the total sales and average monthly sales.
- Use functions to view sales, edit sales, calculate total, and calculate average.
