The exercise instructions here are long -- read them all carefully. if you see an internal scrollbar to the right of these instructions, be sure to scroll down to read everything. given an integer variable i and a floating-point variable f, that have already been given values, write a statement that writes both of their values to standard output in the following format: i=value-of-i f=value-of-f thus, if i's value were 25 and f's value were 12.34, the output would be: i=25 f=12.34 but you don't know what i's value and f's value are. they might be 187 and 24.06. if that's what their values are, the output from your statement should be: i=187 f=24.06 on the other hand, they might be 19 and 2.001. if that's what their values are, the output from your statement should be: i=19 f=2.001 remember: you are given i and f-- that means they are already declared and they already have values! don't change their values by assigning or initializing them! just print them out the way we have shown above. just write one statement to produce the output. remember: in your output you must be displaying both the name of the variable (like i) and its value.

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:
