Write a program that uses key events to make a circle larger and smaller. Your circle should start at a radius of 100 and a position of 250, 250. Each time the user hits the left arrow, the circle should decrease by 10. If the user hits the right arrow, it should increase by 10.

Hint: Use the get_radius() and set_radius() method to change the size of your circle. Find more details and examples on these functions in the DOCs tab.

Challenge: Can you prevent the circle from getting smaller than a radius of 10 and larger than a radius of 400?

7.23 main lab 7 - online shopping cart background this main lab extends the earlier prep lab "online shopping cart part 1". (you should save this as a separate project from the earlier prep lab). you will create an on-line shopping cart like you might use for your on-line purchases. the goal is to become comfortable with setting up classes and using objects. requirements this lab can be done individually or as pair programming. expanded itemtopurchase class (15 points) extend the itemtopurchase class as follows. we will not do unit testing in this lab so we will not be giving you the names of the member functions. create good ones on your own. create a parameterized constructor to assign item name, item description, item price, and item quantity (default values of "none" for name and description, and 0 for price and quantity). additional public member functions set an item description get an item description print the cost of an item - outputs the item name followed by the quantity, price, and subtotal (see example) print the description of an item - outputs the item name and description (see example) additional private data members a string for the description of the item. example output of the function which prints the cost of an item: bottled water 10 @ $1.50 = $15.00 example output of the function which prints the item description:
