(The Stock class) Design a class named Stock that contains the following:

■ A string data field named symbol for the stock’s symbol.

■ A string data field named name for the stock’s name.

■ A double data field named previousClosingPrice that stores the stock price for the previous day.

■ A double data field named currentPrice that stores the stock price for the current time.

■ A constructor that creates a stock with specified symbol and name.

■ The constant accessor functions for all data fields.

■ The mutator functions for previousClosingPrice and currentPrice.

A constant function named getChangePercent() that returns the percentage changed from previousClosingPrice to currentPrice.

Draw the UML diagram for the class. Implement the class. Write a test program that creates a Stock object with the stock symbol MSFT, the name Microsoft Corporation, and the previous closing price of 27.5. Set a new current price to 27.6 and display the price-change percentage.
