There are three more TODO comments in the user interaction loopin the create() method. These three comments reference turning eachone of the three blocks of code in the loop (separated from eachother by blank lines) into methods. Write these three methods. Youshould write a method to get user input for each item the customeris to pay for, a method to update the receipt with the userinformation about each item, and a method to ask the user if theywish to enter another item (goods or services).
Once you have written your three methods, change the userinteraction loop to have just three statements, each invoking oneof the new methods that you have written. Once you have done this,your user interaction loop should be as follows:
statement to invoke a method to ask the user for an itemdescription and charging information for the item statement toinvoke a method to update the receipt with the information justentered by the user about an item keepGoing = an invocation of amethod that asks the user if there is another item to be chargedfor, records their response and returns an appropriatevalue
