Question

Create a program using C++ for a store. It will be a ledger for daily transactions. It should be able to record the transactions on a date.

The transactions will happen at a given time (hour, minute, second). Also, every transaction must have a unique ID that is a number that is randomly generated by the system. *Note that the transaction has an ID, NOT the items. There will be no more than 10 transactions on a date. Within every transaction an item will be sold. Each item should have a name, a cost price, selling price, and all item’s cost price should be more than the selling price to generate a profit. You must also implement the ability to void (delete) a transaction. If 10 transactions have not occurred, then more transactions should be possible. After each day, a list of transactions will be made. The list should include:

The time (hour, minute, and second) in which the item was sold.

The cost.

The name of the item.

The unique ID for the transaction.

Selling price.

Finally, the profit.

A menu should also be implemented within your program, and should allow you to do the following:

Create a new transaction by giving the hour, minute, and second the transaction was made followed by the details of the specific item.

Void (delete) a transaction by entering the ID of the transaction. *Note: The ID can be obtained by viewing the summary of transactions.

Print the summary of all transactions on that date. It should have the time, ID, name, cost, selling price, profit, the average profit for each individual item, and the total profit for that date. When the ‘Print Summary’ option is chosen, another menu should be shown to decide how the summary should be printed. The user should have the option to sort the summary by name, ID, or by increasing order of profit. For sorting, use either binary or selection sort algorithms.
