write a c++ program Use a pretest loop to allow the user to enter data until they input 0 for the purchase amount. Do all of your output in main(). Make it look like this. Don’t forget your underlines won’t be immediately underneath.    Use methods for the following: getPurchaseAmt() Get the monthly purchase amount from the user. Include an error-trap around this input value so the user will have to enter a positive number (0r 0 to end the loop). Return the purchase amount. displayMenu() Display a menu of the membership types for the user to choose from, as follows: Membership Types: Premium Plus Standard Enter choice (1, 2, or 3): This method only displays. There is nothing to return, so it will be a void method. You will call this method from getType(). getType() Call the displayMenu() method and get the membership type from the user. Include an error-trap around the menu and choice so the program will not continue until the user enters a valid choice. Return the choice. calcPoints() Premium members receive 3 reward points for every 100 dollars they spend, Plus members receive 2 reward points for every hundred dollars they spend, and Standard members receive 1 reward point for every 100 dollars they spend. (Hint: Integer division and type casting as int will come in handy for this). Return the number of reward points.

write a c++ program Use a pretest loop to allow the user to enter data until they input 0 for the purchase amount.

Do all of your output in main(). Make it look like this. Don’t forget your underlines won’t be immediately underneath.

Use methods for the following:

getPurchaseAmt()

Get the monthly purchase amount from the user. Include an error-trap around this input value so the user will have to enter a positive number (0r 0 to end the loop). Return the purchase amount.

displayMenu()

Display a menu of the membership types for the user to choose from, as follows:

Membership Types:

1. Premium
2. Plus
3. Standard

Enter choice (1, 2, or 3):

This method only displays. There is nothing to return, so it will be a void method. You will call this method from getType().

getType()

Call the displayMenu() method and get the membership type from the user. Include an error-trap around the menu and choice so the program will not continue until the user enters a valid choice. Return the choice.

calcPoints()

Premium members receive 3 reward points for every 100 dollars they spend, Plus members receive 2 reward points for every hundred dollars they spend, and Standard members receive 1 reward point for every 100 dollars they spend. (Hint: Integer division and type casting as int will come in handy for this). Return the number of reward points.
